more This update helps you take better care of your plants: find out what's wrong, know the right time to harvest and keep GrowerHelper on your home screen.
What's new
• Plant health: tap "something wrong? find out" on the add button and answer 2 or 3 questions (what you see, which pattern, where it started). The app shows the most likely causes, how to confirm, what to do and how to prevent it, all offline and without AI. One tap logs the problem with photos and severity, and it stays open until you mark it resolved.
• Problem log: see what's still open and how long each problem took to fix. Problems also show up in the feed and on the report charts.
• Harvest window: the app counts your days in flower against your strain's flowering time and shows how long is left. In the trichome check you pick what you see under the loupe (clear, cloudy, amber) and the app tells you if it's early, ready or going past peak, and reminds you to look again.
• Home screen widget: your active grow at a glance, with the day of the phase, the last watering, the next reminder and buttons to water, take a photo or add a note. With the app lock on, it turns into a neutral card with no data.
• App icon shortcuts: long press the app icon to log a watering, take a photo or add a note right away.
• Appearance: light, dark or follow the system, plus two new skins: Blackout (true black, great for OLED screens) and High contrast.
• Smarter plant + button: health, trichomes and aroma on the plant sheet, with suggestions for what to do now (open problem, flowering, days without water or a photo). Menus and pickers now close with a swipe down, and the Add screen is ordered by what you use most.
Still 100% offline, no tracking. Happy growing!
2.0.77 Oct 12
This update brings Memories: a video of your grow's best moments, built right on your phone.
What's new
• Memories (grow recap video): tap the memory button in the Gallery, pick the events you want (feeding, pruning, harvest...) and the app assembles a vertical video from oldest to newest, mixing photos, videos and dated event cards. Photos get a slow zoom, videos play with their original audio, and everything is joined by soft transitions. The video is rendered on the device itself, with no cloud and no account, and it lives in the same private space as your photos: nothing leaves your phone unless you share it.
• Shareable grow card: a poster with cover photo, strain, days, dry yield, g/day, plant count, rating stars and the aroma radar. You can now swipe the cover and choose which photo goes on the poster. Export it as a PNG through the share sheet (WhatsApp, Instagram, save...).
• Example grow: one tap builds a complete 15-week fictional grow, with photos, charts backed by real series, the weekly journal and a finished harvest, so you can explore the app without waiting weeks for data. One tap removes it, and your own data is never touched.
• Simpler first run: a single screen with the privacy promise and three ways to start. Choosing "already growing" or "planting soon" now walks you step by step through creating the grow and the plant.
• The app-lock decoy is convincing now: opening with the decoy password (or an empty password) shows a garden journal that looks genuinely used, with a cover photo, plant cards and recent photos. It still has no way through to the real app.
Still 100% offline, no tracking. Happy growing!
2.0.76 Aug 2
This update redesigns grow planning and makes the app open instantly.
What's new
• Planning is now per grow: set the schedule from the + button (veg and flower weeks, watering frequency) and the app suggests the cycle steps (LST, transplant, topping, flip, defoliation, flush, trichome check, harvest, drying and curing). Every step is yours: rename it, change its date and time, rewrite the note, delete it or create your own from scratch.
• A much cleaner planning screen: a one-line summary card with the predicted harvest date and a vertical timeline grouped by phase (veg, flower, harvest and cure), with a "today" divider between what's done and what's next.
• Full-screen step editor: change any step's event type and pick the exact date and time with the native pickers. Each step keeps its own reminder time.
• Plan reminders truly linked: they show a "plan" tag in the tasks screen, tapping one opens the plan, and deleting or pausing one disables its step. Saving the plan again won't bring it back.
• Tasks organized in sections: recurring and planned are separate, with tap to edit instead of delete and recreate.
• A more direct first run: two screens and the question "how do you want to start?" take you straight to your first action.
• The app opens instantly: the launch animation is gone.
• Libraries with tap to edit, a type filter in the strain library, and faster loading recipes.
• Settings: a rate GrowerHelper button, a website link and the app version in the footer.
Fixes
• Deleting a crop, a plant or the plan no longer leaves orphan reminders firing in the system.
• The store review prompt now actually works.
Still 100% offline, no tracking. Happy growing!
2.0.73 Jul 12
This update brings the Grow Plan: you plan, the app handles the reminders.
What's new
• Grow planning: set veg and flower weeks and see a visual timeline with the predicted harvest date. The plan is stage-aware (seed, veg or flower), so the dates make sense.
• Auto-generated reminders (opt-in): from the plan, the app proposes tasks for LST, transplant, topping/FIM, flip, defoliation, bud support, flush, trichome check, harvest, drying and curing. Everything is off by default and each reminder is removable one by one in the preview.
• Watering schedule: say how many times a week you water (e.g. 3x) and the app creates a recurring feed reminder on days spread across the week.
• 30 preloaded popular strains: Critical Kush, Gorilla Glue, Amnesia Haze and more, with veg/flower weeks, height, yield and THC/CBD. A library picker next to the strain field opens the whole catalog, with search.
• Strain card: when you pick a strain, a card shows type, flowering, yield, THC and height, and takes you straight to the details, now editable.
• Smart filters in the feed and the gallery: one simple picker filters by plant, by event and by life cycle (germination, young, flower, mature). In the gallery, each photo knows the plant's stage when it was taken.
Fixes
• A toast no longer gets stuck inside full-screen forms.
Still 100% offline, no tracking. Happy growing!
2.0.72 Jul 1
This version makes search smarter and reports more complete.
What's new
• Multilingual search: find events by typing the action name in any of the 5 languages, even when the word isn't in a note. It ignores accents ("extracao" finds "extração") and c
ombines terms ("feeding Biobizz").
• Search now opens more entry types: height, lamp distance, light intensity, drying and curing, aroma and effect profiles, plant added and removed.
• Crop report opens with a summary strip: total days, days in veg and flower, plant count, and — once you close with a dry weight — yield and grams per plant.
• Report charts draw the phase target band as a strip behind the line, and the event markers (feed, prune, transplant, light, stage) now have a legend.
• Lightbox video controls: a bar with play/pause, elapsed time, a draggable scrubber and duration.
• Re-tapping the active tab (Today, Crops, Add, Gallery, Settings) scrolls that screen back to the top.
Faster & lighter
• Plant detail and the feed now use virtualized lists and database-side filters, and returning from an edit keeps your scroll position.
• Contrast-safe accent colors (readable in light mode) and bigger touch targets on chips.
Fixes
• Fertilizer totals no longer multiply the dose by the plant count.
• Days in veg/flower use the same phase boundaries as the phase bar and journal.
• The crop panel's VPD only pairs temperature and humidity measured within 48 hours of each other.
Still 100% offline, no tracking. Happy growing!
2.0.70 Jun 16
This version makes the app yours, with smarter reports to match.
What's new
• Skins: pick the app's color in Settings. Forest (classic green), hydro (blue), kush (pink), cherry (red), harvest (orange) or smoky (grey). Each skin recolors the whole app (ev
ents, charts, buttons) and combines freely with light or dark mode.
• Moon calendar redesigned with a grower phase guide: what each phase favors (germination, transplant, pruning, flush, harvest), in a hero card with an 8-phase legend.
• Richer fertilizers report: a donut of your last feed's mix plus per-fertilizer cadence ("used 11×, every ~4 days").
• Event markers on charts: subtle lines show when you fed, pruned, transplanted or changed the light. Cause and effect right on the curve.
• Light intensity (PPFD or lux) with DLI derived from the photoperiod and its own report tab.
• Week Journal with an activity insights card.
• VPD calculator: a phase range table and smarter tips when the reading is off target.
• Redesigned utility screens (water, weight, NPK) with a searchable one-tap fertilizer picker.
• Logging temperature or humidity opens with your last reading, with no "out of range" badge while you type.
Fixes & improvements
• A weekly check-in reminder created during a check-in now starts next week.
• VPD sliders no longer jump on first touch.
• Fertilizer doses always read ml/g; °F respected on the Week Journal and crop panel.
• Plant phase history reads newest-first.
• Refreshed aroma/effect profiles and feed cards, plus many report layout fixes.
Still 100% offline, no tracking. Happy growing!
2.0.67 Jun 10
What's new
• Long-press an entry in the feed to quickly edit or delete it.
• A grow's phase now follows the plants' actual stage (no more mismatched vegetative/germination labels), and tapping a temperature or humidity tile pre-fills the value already shown.
• Curing burp reminders now schedule as a single series (not one per day), and there's a new weekly check-in reminder.
• Adding several plants at once shows as a single feed entry.
• The phase bar now appears on the crop panel and report, difficulty + rating show on the plant, and the crop panel / reports got a cleanup plus various layout fixes.
Still 100% offline, no tracking. Happy growing!
2.0.65 Jun 6
This update puts VPD at the center of your grow and gives you control over video.
What's new
• Week Journal: see your grow week by week, with a week navigator, a "spent N days" phase bar (germination, veg, flower, harvest) and cards showing each week's avg temperature/humidity/VPD, water, photos and events.
• Height & lamp distance: log these and track them on the charts, which now have a toggle to view any metric by grow week.
• Grow identity: set a difficulty, rate a finished grow with stars at close, and list your gear (tent, fan, filter, nutrient line…). The rating also ranks grows in the comparison.
• Weekly check-in: log the week's temperature, humidity, height, and a note in one quick sheet.
• VPD at a glance: the crop panel now shows VPD (vapor pressure deficit), colour-coded by phase: green in target, red out of range. When it's off, the app tells you how far to move humidity or temperature to get back in range.
• VPD calculator: drag temperature and humidity and watch leaf VPD land in the target band on a colour-coded bar. A day/night button applies the leaf-temperature offset (the canopy runs cooler than the air under LEDs by day).
• Video quality (Settings › Photo & video): pick Low (480p), Medium (1080p) or High (4K). The app applies the right settings for each platform (Android and iPhone).
• More polish: the Add screen is now a clean grouped list (easier to find an action) and plant stats are tidier.
Still 100% offline, no tracking. Happy growing!
2.0.63 Jun 6
This update brings powerful tools to organize your grows and protect your privacy.
What's new
• Move plants between crops: transfer a plant with its full event and photo history to another crop. Reachable from the Action grid or from a plant's profile.
• Compare grows (Profile): a leaderboard of all your finished crops ranked by yield, days to harvest, or g/day. Horizontal bar chart.
• Encrypted backups: optionally protect your export file with an AES-256 password. Compatible with 7-Zip, Keka, WinRAR.
• App lock with decoy: protect the app with a password and optionally a second "decoy" password that opens a fake tomato app. Plausible deniability.
• Strain library: full per-genetics history — average days, yield, aroma and effect profiles. Type-ahead suggestions when adding a plant.
Fixes
• QR scanner close button no longer sits under the notch / Dynamic Island on iOS.
• Photo quality slider now shows the actual value and works without jumping.
Still fully offline, no tracking. Happy growing!
2.0.62 Jun 5
This update makes photos much faster and puts you in control of your privacy.
What's new
• Instant photos: capturing and saving no longer stall; the photo shows up immediately and processing runs in the background.
• Photo options (Settings): choose to strip EXIF/GPS metadata and turn on compression with adjustable quality. By default we strip EXIF and compress at 85% (no visible loss). Want the raw file? Just turn it off.
• NPK / EC calculator: add up the NPK of a fertilizer mix for a water volume and see N-P-K in mg/L, plus estimated EC and TDS.
• QR labels for plants: generate, print or share a QR code and scan it to jump straight to the plant.
• Aroma & effect profiles: log notes and effects (0–5) any time, with a radar chart.
Fixes & improvements
• pH/EC no longer disappear in the crops tab.
• Various form smoothness polish.
