v1.43 — PLANTS, PROPERLY NAMED Your logged plants now show their scientific name front and center — Vallisneria spiralis, not just "Val". The common English name appears alongside as a secondary label. Plant search also now recognizes scientific names, so you can search in Latin if that’s how you think about your plants. LIGHT & CO₂ AT A GLANCE Plant care cards color-code your requirements at a glance. Light: red for high, amber for medium, teal for low-medium, blue for low. CO₂: red if required or strongly recommended, amber if beneficial, teal if a little helps, blue if it’s not a factor. We also updated the plant database — Java Fern, Buce, Cryptocoryne, Water Wisteria, Fissidens Moss, Bacopa, and Pearl Weed are now correctly flagged as benefiting from CO₂. YOUR TANK, AT A GLANCE A new Inhabitants tile on the Tank tab shows your animals and plants in one snapshot — counts, types, and individual species pills. Tap the edit button to control what appears and in what order. CO₂ is now embedded directly in the Last Water Test card. It shows your calculated ppm, zone badge, a gauge bar with an animated needle, bubble animation, and a trend arrow comparing to your previous test. ANIMALS, RETHOUGHT The Animals summary is redesigned: total count, types, and group count at a glance, with pill tags for every group. Group photos now appear in the card header and expanded view. Group quantity is now a direct field — type how many you have. You can still track individual animals inside an expanded group using the new “+ Add Individual” button. TEST SETTINGS Ammonia and Nitrite are now optional — toggle them off in Test Settings if you don’t test for them. Grading is also tightened: any reading above 0 is immediately flagged red. The old 0.25 tolerance is gone. POLISH — Filter flow rate now shows L/h or L/min (selectable) for metric users — Param names (Ammonia, Nitrite, Nitrate) now appear in your app language throughout — Plant search suggestions now show scientific name, common name, light, and CO₂ info — Water change volume preview and several labels now fully localized Free. No login. No subscription.

v1.42 — QUICK NAVIGATION HOME TILE JUMP Every "Last X" tile on the home screen — Test, Change, Cleaning, Dose, Feed — now has a colored chip showing how long ago. Tap it and you jump straight to that tab with the entry already expanded. No hunting through history. TAP TO GO BACK The full header bar on the Aquarium Specs page, Settings, parameter pages, and achievement pages is now tappable to dismiss — not just the back button. If it looks like a nav bar, the whole thing goes back. BUG FIX Push notifications were sending "TideLog" as the app name — most visible on Apple Watch. Corrected to TankLog. ALSO Tab transitions animate at a slightly slower pace now. Animals and Plants pages were missing the fade-in entirely; fixed. Free. No login. No subscription.

v1.41 — FEELS RIGHT AQUASCAPE PHOTO ZOOM Tap your tank photo and it opens full screen — a clean overlay with your photo filling the display. Tap anywhere to dismiss. Now when you want to really see what's going on in your aquascape, you can. CO₂ GAUGE IS TAPPABLE The needle dot on the CO₂ gauge wasn't doing anything when you tapped it. Now it does — opens the CO₂ parameter page, same as the arrow beside it. If it looks tappable, it should be. ACTIVITY CALENDAR The day panel now uses the actual nav icons next to each logged event — water test, water change, cleaning, dosing, feeding — instead of plain colored dots. The "Today" button also got a calendar icon. Small touches, cleaner read. Free. No login. No subscription.

v1.40 — ACT ON IT ACTIVITY CALENDAR — NOW ACTIONABLE Care schedule due dates now appear on the Activity Calendar. Each due date shows its status — Upcoming, Due Today, or Past Due — and tapping any overdue or due-today item jumps you straight to the log form. Your calendar isn't just a history view anymore: it tells you what needs doing and gets you there in one tap. TEST LOG — BLANK SLATE Water test fields now open blank, so you're always entering real readings — not staring at last session's numbers already filled in. A new Recent section at the top lets you pull in your last test with one tap if you want a starting point. And when a field is empty, a subtle hint shows what you measured last time. Free. No login. No subscription.

v1.39 — YOUR CALENDAR ACTIVITY CALENDAR Tap the date in the header to open the Activity Calendar. Every day you've logged something gets a color-coded dot — purple for tests, blue for changes, tan for cleaning, rose for dosing, gold for feeding. Tap any day to see what was logged. Tap a specific entry and the app jumps straight to it in the history tab — card expanded, scrolled into view. A Next Due banner shows your most pressing upcoming task, and there's a tank picker if you keep more than one aquarium. BADGE ANIMATIONS The five achievement badges that were still static now have icon animations, each matched to what the badge represents: a flame flicker for Resurrected, a rocket rise for Comeback, a radar pulse for Perfect Test, a clipboard tilt for Full Panel, and a gauge rock for Steady Hand. POLISH The Previous Reading section on the CO₂ parameter page now shows the earlier reading in the correct CO₂ zone color — green, yellow, or red — rather than the grade color it was using before. Free. No login. No subscription.

v1.38 — READINGS, ROUNDED OUT CO₂ PREVIOUS READING When you tap the CO₂ Level card, you'll now see a Previous Reading section — the calculated CO₂ ppm from the test before, with a trend arrow and date. Matches the format every other parameter page already had. PARAM TRENDS RECORD COUNT The Param Trends chart on each parameter page now shows a record count in the top right — "4 records" if you have a handful, "last 60" if you've hit the display cap. Quick context for how much data is behind the line. BUG FIX The trend arrow on the Previous Reading section was showing the wrong direction — it was repeating the current test's arrow instead of computing the trend for that earlier reading. Fixed. Free. No login. No subscription.

v1.37 — KNOW THE TREND PREVIOUS READING Tap any water test tile — pH, Ammonia, Nitrite, whatever you track — and you'll now see two readings instead of one. The top label is now LATEST READING. Below it, a new PREVIOUS READING section shows the value from the test before, a trend arrow (↑ ↓ →), the grade in its color, and the date of that earlier test. At a glance: is your water chemistry improving, holding steady, or heading the wrong way? BEST STREAK DATES On the Clean Streak and On-Time Streak achievement pages, if your current streak isn't your personal best, you'll now see the record: a trophy icon, "Best: 6x", and the exact date range it ran — "Jun 22 – Jul 27". If the best was from a previous year, the year is shown. Something to aim for. POLISH The shimmer on achievement badge pills now sweeps through using the badge's own color at low opacity, instead of the grey/white wash that was making the text hard to read while animating. BUG FIXES The first data point on Param Trends was clipping behind the y-axis. Fixed. The On-Time Streak badge now clears immediately when your test window turns overdue, rather than waiting until the next log. Free. No login. No subscription.

v1.36 — YOUR TANK, YOUR LOOK COLOR ASSIST A new per-tank toggle in Tank Specs lets you turn off the health-colored borders on all your tiles — Grade, Last Test, Care Schedule, CO₂, and your care log cards all go back to neutral grey. Useful if you find the color signals distracting or just prefer a cleaner look. Your data and grades don't change — only the borders. ACHIEVEMENT COUNT The Overall Health tile now shows how many badges you've earned at a glance, right next to the achievements header. DATES, EVERYWHERE Every care tile now shows the actual date (not just "X days ago") in the same consistent format — Last Changed, Last Dosed, Last Fed, Last Cleaned. Next Due tiles also show the exact upcoming date. POLISH The back button on Achievement pages now nudges left — consistent with the rest of the app. Param Trends shows the record count right inside the selector button. Free. No login. No subscription.

v1.35 — NUDGE IN THE RIGHT DIRECTION HINTS THAT SHOW THE WAY Back chevrons now give a gentle double-nudge so you always know where to tap. Collapsed sections nudge down to invite opening. And when something's due or overdue, the → arrows nudge right — the urgency is visible before you even read the label. SMARTER CO₂ CARD The CO₂ level card now stays hidden until KH testing is enabled. No more showing up on a fresh tank before anything's been set up. NEXT DUE — TAP TO ACT Tapping anywhere on your care tiles used to open the log form. Now only the "Next Due" label does that — so browsing your dashboard doesn't accidentally drop you into a form. POLISH Fixed a confusing "What to Do" message on Ammonia and Nitrite that said levels were at zero even when they weren't. Free. No login. No subscription.

v1.34 — FIVE NEW BADGES TO CHASE NEW ACHIEVEMENTS Five new badges join your Overall Health tile: Resurrected for the biggest possible jump, an F straight to an A. Comeback for any big two-grade leap. Perfect Test when every parameter reads ideal. Full Panel for a complete reading with nothing skipped. And Steady Hand for a rock-steady pH. Swipe the badge row to see them all. A LIVELIER DASHBOARD Tappable spots now give a gentle nudge so it's obvious what you can tap — parameter tiles, the CO2 card, and every "log first" or "set up schedule" link. Your most recent chart point and the CO2 needle both get a subtle pulse too. TAP TO ACT Your Last Change, Last Dosed, Last Fed, and Last Cleaned tiles are now tap-anywhere. Tap to jump to that tab, and if something's overdue or nothing's logged yet, the form opens right away. Free. No login. No subscription.

v1.33 — LEARN YOUR BADGES TAP TO LEARN MORE Every achievement badge on your Overall Health tile now opens its own page — see when you earned it, exactly which tests earned it, and how to keep it going before it resets. SMOOTHER CHARTS Param trend charts on your Tank tab and parameter pages now fade at the edges when there's more history to scroll to — the same subtle cue already used on your achievement badges. POLISH Fixed a glitch where sparkle animations on a top grade could burst rapidly instead of twinkling gently. Achievement badge colors also read more clearly in light mode. Free. No login. No subscription.

v1.32 — EARN YOUR STRIPES ACHIEVEMENT BADGES The Overall Health tile now awards animated badges for consistent care. Grade Up celebrates back-to-back water quality improvements. On-Time Streak rewards testing and maintenance on schedule. Clean Streak marks a run of top grades. THEY MOVE Every badge arrives with a shimmer sweep, a spinning glow border, and its own icon animation — the alarm wiggles, the arrow bounces, the sparkle twinkles. All timed together. TOGGLE ANYTIME Head to your aquarium's specs and uncheck Achievements to hide the badges without losing your progress. Free. No login. No subscription.

v1.31 — KNOW YOUR NUMBERS SEE YOUR TOTALS Every history tab — Tests, Changes, Cleaning, Dosing, Feeding — now shows how many you've logged right next to the header. A quick way to see your tank's story at a glance. QUICK RECENTS FOR CLEANING The Cleaning log now offers the same quick-fill shortcuts as Dosing and Feeding — tap a past entry to instantly refill the type and notes. Perfect for repeat jobs like trimming the same plants. SMALL FIXES Renamed "I Want to Log" to "Log Preferences" in Tank Specs, and fixed a translation bug that had it reading as "log in" instead of "track" in several languages. Free. No login. No subscription.

v1.30 — TIDYING UP TRANSLATIONS, TIGHTENED A handful of labels across the Dosing and Animals tabs weren't showing in your language — some dosing buttons stayed in English, and a few badges showed raw text instead of the translated label. All fixed, across every supported language. SMALL FIXES THROUGHOUT Cleaned up a couple of misaligned rows in Tank Specs and made sure every reorderable section has a consistent divider line between items. Free. No login. No subscription.

v1.29.1 — SMOOTHER NAV Fixed the tab-switching animation so the wave rolls and settles correctly on iOS — a few of you saw it stutter or skip in the last update. Free. No login. No subscription.

v1.29 — YOUR TANK, YOUR WAY I WANT TO LOG TankLog tracks five categories of care — Tests, Changes, Cleaning, Dosing, Feeding — plus Animals and Plants. But not every tank needs all seven. If you don't dose, don't track dosing. If you don't have animals, don't see the Animals tab. The new "I WANT TO LOG" section in Tank Specs lets you turn any category off. The nav tab disappears, home cards go away, care schedule rows go quiet, and notifications stop. Re-enable it and everything comes back. Your data is never deleted. REORDER YOUR TABS Use the arrows in the same section to set the order your tabs appear in. Feeding first? Tests last? Your call. Tank is always first — the rest are yours to arrange. Settings are per tank, not app-wide. Different tanks, different configurations. Free. No login. No subscription.

v1.28 — NAV, REIMAGINED A LITTLE LIFE IN YOUR TABS Tap any tab and a wave now rolls across it before settling into place, while the icon and label rise up as if surfacing from the water. Small touches, but they make moving around TankLog feel a lot more alive. GRADE AT A GLANCE The Last Water Test tile on your Tank tab now shows a small grade badge right next to the date — so you can see how your tank is doing even after you've scrolled past your care schedules. ONE LESS THING TO NOTICE The Log Dose button now turns green when you haven't set up a dosing schedule, matching Log Cleaning. One less inconsistency to wonder about. Free. No login. No subscription.

v1.27 — SMOOTHER EVERYWHERE TAP TO EXPAND Your Tank card and every history card — tests, water changes, feeding, dosing, cleaning — now expand with a single tap anywhere on the card, not just a small arrow. Edit and delete buttons stay put, so you won't trigger them by accident. EDITING, REFINED Editing a past entry now looks and feels just like logging a new one, with the same layout and field order. Editing a water test also shows live grading and a CO₂ zone estimate as you adjust your numbers. FIRST-LAUNCH POLISH The welcome setup screen now matches the rest of the app — toggles and buttons styled like Settings, with Appearance moved right where you'd expect it. BUG FIXES Fixed the Temperature tile not showing the correct grade color in °F, and fixed a blank info page when tapping the info icon on a test tile. Free. No login. No subscription.

v1.26 — PARAM HISTORY, RIGHT WHERE YOU NEED IT SEE THE TREND BEHIND EVERY READING Tap any water test parameter on its info page and you will now find a trend chart at the bottom — the same scrollable chart from your Tank tab, but focused on just that parameter. Tap any point for the date, value, and grade. If you have not logged enough tests yet, a short message tells you how many more you need. KNOW WHEN YOU LAST CHECKED Every parameter page now shows the date of your last reading next to the value and grade, so you always know how fresh your numbers are. SETTINGS, REORGANIZED Appearance (dark/light mode) now sits above Notifications in Settings, making it quicker to find when you want to switch themes. Free. No login. No subscription.

v1.25 — SMARTER FEEDBACK + CLEANER NAVIGATION YOUR TANK TELLS YOU HOW IT'S DOING Log a water test and TankLog now responds to the result, not just the action. A-grade water gets a celebration — your tank is thriving. B-grade gets a thumbs-up. C or F tells you to check your levels. The response matches the moment, whether things are going well or need attention. LOAD MORE, STAY ORIENTED The history load-more buttons have been redesigned. Each one is now a full-width pill, color-coded to match its tab — purple for tests, blue for changes, tan for cleanings, rose for dosing, gold for feeding. A down arrow shows how many entries are showing and how many are left. Nothing about the data changed; it just became a lot easier to navigate. DISMISS OVERDUE ALERTS If your Tank tab shows overdue care alerts and you already know about them, there's now a dismiss button. Tap the × and the strip closes for that session. Switch tanks and it resets — a fresh check for each tank, not a permanent snooze. TAB LABELS, CLEANED UP Tests and Changes have been renamed to Test and Change — singular, like the other three tabs. Clean, consistent, and a little less crowded. Free. No login. No subscription.

v1.24 — CUSTOM LABELS + TILE CONTROLS MAKE "OTHER" ACTUALLY USEFUL Dosing, cleaning, and feeding all have an Other option for entries that don't fit the standard types. The problem: log three "Other" doses in a row and you can't tell them apart. v1.24 fixes this with a custom label field. Select Other and a text box appears. Type what it actually was — "Excel", "leaf litter", "conditioning treatment" — and that label shows in your history instead of the generic Other. Feeding has the same improvement for the For field. If you're feeding something outside the standard categories, name it and TankLog remembers. HIDE YOUR TEST TILES Test Settings now has a Hide/Show toggle. Switch it off and the three test-related tiles disappear from your Tank tab — Last Water Test, CO₂ Level, and Param Trends. Your Tests tab and logging stay completely untouched. It's a display preference only. REORDER YOUR EQUIPMENT The Equipment section in Tank Specs now has the same up/down reorder arrows as the Care Schedule. Set the order of Lighting, Filtration, CO₂, and Heater to match how you think about your tank — and the equipment tile on your Tank tab follows that order. Free. No login. No subscription.

v1.23 — WATER TEST GUIDANCE KNOW WHAT TO DO WITH YOUR RESULTS Logging a water test is the first step — knowing what the numbers mean for your tank is the second. v1.23 adds a guidance page for every test parameter. Tap any tile on the Last Water Test card to open it. Each page is built around your actual reading. Your last result and its grade, the target range to aim for, and specific advice based on exactly where you landed — whether that's in range, too low, or too high. If your nitrate is elevated it walks you through the most effective steps to bring it down. If your pH is low it explains the most likely causes and what to adjust first. If everything is dialed in, it tells you that too. CO₂ HAS ITS OWN PAGE For tanks running CO₂, the CO₂ Level card now opens a guidance page showing your latest estimated dissolved CO₂, the zone it falls in — Very Low through Risk for Livestock — and specific advice for that zone. Free. No login. No subscription.

v1.22 — CLEANING LOG + CUSTOMIZATION A FULL CLEANING TAB Tank maintenance goes beyond water tests and changes. v1.22 adds a dedicated Cleaning tab — log every scrub, scheduled or spontaneous. Set up cleaning schedules by type: Full Clean, Filter, Gravel/Substrate, Glass, or Other. Each schedule tracks its own due date and surfaces on the Care Schedule alongside your tests, changes, dosing, and feedings. When a cleaning is overdue, the same red alert banner on the home screen fires — so nothing slips. The home screen adds a Last Cleaned card showing what type of cleaning was done, any notes you left, and when the next one is due. Cleanings export and import with the rest of your tank data. You can edit any entry after logging it. CUSTOMIZE YOUR TANK TAB Tank Specs now includes Hide and Show controls for every tile on your Tank tab. Equipment tiles — Lighting, Filtration, CO₂, Heater — and Care Schedule rows — Water Test, Water Change, Feeding, Dosing — each have their own toggle. Don't use CO₂? Hide it. Running a simple planted tank? Show only what you actually track. SMOOTHER DRAG-TO-REORDER Reordering test parameters in Test Settings got a full overhaul. Tap and hold a parameter tile and it lifts as a ghost. The surrounding tiles smoothly slide out of the way to show exactly where it'll land when you release. Free. No login. No subscription.

v1.21 — CONTROL REORDER YOUR TEST PARAMETERS Every aquarium is different. For a planted tank, CO₂ and nitrate are the numbers that matter most. For a shrimp tank it's pH and GH. But until now, the order your parameters appeared in was fixed — whatever the app decided was the order you got. v1.21 changes this. In Test Settings, you can now drag parameters into any order you want. Press and hold to pick one up, then drag it to where it belongs. That order carries through the entire app: the test log form, your history entries, the param trends chart. Set it once and the whole app reflects your priorities. At the bottom of Test Settings, the Reset to Defaults button has been redesigned — full-width with a reset icon, so it's immediately clear what it does. DOSING REMINDERS Dosing schedules track what's due, but until now you had to open the app to find out. v1.21 adds dosing reminders. Enable them in Settings alongside your existing test, water change, and feeding reminders. When a dose is coming due, you'll get a notification. If you're setting up the app for the first time, dosing reminders are now part of the initial setup question alongside the others. SEND FEEDBACK Found a bug? Have a feature idea? Something that should work differently? Settings now has a Send Feedback option. Choose a type — bug report, feature request, or general feedback — write a quick summary, add some detail, and send. It goes directly to the developer. No email address, no account needed. Free. No login. No subscription.

v1.20 — TEMPERATURE TRACK WHAT ACTUALLY MATTERS Most freshwater tanks run a heater. But until now, there was no way to log your actual water temperature alongside your test results — no grade, no history, no trend to review when something goes wrong. v1.20 adds temperature as a full parameter. Enable it in Test Settings and Temp appears in your test log form alongside pH, ammonia, nitrite, and the rest. Log a reading and it's graded against your preferred range. It shows up in your test history. The param trends chart starts building a temperature line over time. TEMPERATURE IN YOUR UNITS Every temperature value in the app now respects your metric or imperial setting — and switches live when you change it. Set your preference to imperial and temperature is shown in °F throughout: the test log form and its ideal range hints, the last test summary card, each history entry, and the param trends chart — axis labels, dot values, and the tooltip. Flip to metric and everything shows °C instead. Values are always stored in Celsius internally, so the conversion is applied at display time only. Nothing is re-entered, nothing is lost. New tanks start with Temp enabled by default. So do tanks reset to defaults. Most people don't start their aquarium hobby with a KH or GH test kit. Everyone has a thermometer. PARAM TRENDS IMPROVEMENTS The trend chart has two updates that make it more useful. The chart now fills the full width of its container, adjusting responsively to your screen size. Previously it was a fixed-width box regardless of the device. More importantly, the chart now only plots data for the parameter you're viewing. If you haven't logged pH in several sessions but have been logging temperature, the temperature chart doesn't show dots where other tests were logged and Temp was absent. Each parameter chart is built from its own readings only. For a newly enabled parameter, the chart starts cleanly from the first real value you log. QUICK SETTINGS FROM THE TEST FORM When the log water test form is open, a small edit button now appears in the header next to the collapse arrow. Tap it to jump directly to Test Settings — useful if you want to enable a new parameter without leaving the test tab and losing your place. Free. No login. No subscription.
