If you are a Founding Member, the Classic theme now comes with a color of your own. Open Settings, switch to Classic, and pick the accent that feels like you. Your color flows through the main buttons across the app and into Your Sky, so the whole picture takes on your shade. Chartreuse stays the default, so nothing changes unless you want it to. We also gave Your Sky a small polish so its light and the caption beneath it display a little cleaner. The app stays completely free. This is a small thank you for the members who chose to support it.

Still 100% free. Version 2.7.0 introduces Your Sky. Every dose you log and every week you show up becomes light in a sky that is yours alone. The more you track, the brighter it shines. We think it's a nice way to see how far you've come without making you feel guilty about quiet weeks. You'll find it on your Today tab, and it opens full screen whenever you want to sit with it. Your sky only grows when you keep logging and the rest of this release is about making that easier, starting with your fridge. BAC water inventory now lives right beside your peptides. When you reconstitute a vial you can choose specific BAC water inventory. The other half of easy tracking is a schedule that bends when life does. When you travel, take a break, or shift a dose, you can clear the scheduled doses you were never going to take, right from your Full Dose Calendar. Your adherence stays true to what you actually did, and a change in your routine never comes back weeks later as a wall of misses you never really missed. Registration is easier too. Peptide Tracker now offers signing in with Google so that you don't have to type and remember a password.

Still 100% free. Version 2.5.0 adds progress photos. You judge a protocol by how your body changes, and until now the app could only show you numbers. Progress photos put the visual side of tracking right next to your doses and weigh-ins. The camera is built so every week's shot lines up with the last. A centerline and a guide line you can drag keep your framing steady, and a faint ghost of your last photo at the same angle sits over the live view so you can line it up before you shoot. Tag each angle, use the timer or flash, and your shots land in a gallery grouped by month that you can filter by angle. Open one and swipe to walk that angle through time, or pick any two and compare them side by side, then share the result. Once a week goes by since your last photo, the app gives you a gentle nudge to take the next one. This release also adds dosing in International Units. Some compounds are measured in IU instead of by mass, and now you can set an IU dose, add an IU vial, and get the right draw for it. IU and mass stay on separate rails, so the two never mix. Your Today tab now tells you how many units to draw for the vial you are actually holding, so you are not doing milligram math in your head right before an injection. When you keep a compound at two different strengths, the card shows both so you grab the right one. You can also see your next two weeks at a glance on the protocol screen, so you know which days you are dosing and which one is today instead of reading a five on, two off rule and guessing where you are in it. And if you fall off a cycle after a missed dose or a break, you can set the day you are picking it back up, and the schedule just follows along without touching your start date or titration. Your dose history is easier to get through too. You can now filter it down to just the doses you took, missed, or skipped instead of scrolling past everything.

Still 100% free. Version 2.4.0 adds multi-block schedules. People dose the same protocol differently across the week. You might take a higher amount on Monday and a lower one on Thursday, or take it in the morning some days and the evening on others. You can now build that into one protocol instead of creating several. Each block carries its own days, times, and dose, and your protocol detail and stack views show every block at a glance. Your schedule is also clearer to read. A dose on your Today tab now shows whether it is due today, coming up after today, or running late, so you can tell at a glance which doses are current and which are still ahead. Forms are clearer too. When something needs fixing before you can save a protocol, the field is highlighted and the screen scrolls straight to it, so a blocked save is never a mystery. Sign-in and other errors now appear in a clear message instead of slipping by. This release also gives protocol dates their own card with a one-tap shortcut to set a cycle's end date.

Still 100% free. Version 2.3.1 is a small fix release. Your Today tab and calendar now update themselves. Before, they would occasionally need a manual refresh to show a change right after you edited a protocol or logged a dose. Now that happens automatically.

Still 100% free with no features behind paywalls. Peptide Tracker remains free with no ads, subscriptions, or paywalls. Version 2.3.0 adds better injection site tracking. You no longer have to open each dose log to remember where you injected. Your injection sites now live in one place, each one showing how many times you have used it and when you last did, so rotating sites is easy to keep track of. Your last injection site and last weigh-in also appear on the Today tab, and your dose history now shows the site for every dose you log. This release also adds as-needed dosing. Some peptides you take on a fixed schedule, and some you take only when you need them. You can now create an "as needed" protocol that has no schedule and no reminders. It gives you a card on your Today tab that stays available all day, so you can log a dose the moment you take it and see when you last took one. As-needed protocols describe timing only, so they never count for or against your adherence. Also new: • A reorganized Settings screen that groups related options together

Still 100% free Peptide Tracker remains free with no ads, subscriptions, or paywalls. Version 2.2.0 adds three new features (including a familiar old friend). 1. Keep track of your peptide inventory in powder form You can now add a vial before it is mixed and keep it in your supply as powder, then reconstitute it right in the app when you are ready to start. Filters separate what is mixed from what is not, so a glance tells you what is ready to dose. Adding a blend is simpler too. You enter the amounts per component or as a single total, whichever the label gives you. And every log screen now previews the exact amount to draw, blends included, so the syringe lines up with the dose you actually intend. 2. Track your weight over time This release also starts tracking your weight. Log a weigh-in to follow your trend over time, and you can add past days too. Weigh-ins can be found on the Today tab as well as in your Settings. 3. A re-introduction to a new (but familiar) theme Finally, there is a new-ish look. You can now choose the "Classic" theme in your Settings. This is a light theme that brings back the original Peptide Tracker color palette that many of you grew to love when we first started. Also fixed: • Opening a log from Dose history now shows the day it was scheduled for • A handful of smaller fixes and under-the-hood polish

Still 100% free Peptide Tracker remains free with no ads, subscriptions, or paywalls. Version 2.1.0 puts your adherence front and center. Every protocol now has its own adherence card, so you can finally see how consistently you are actually following it instead of guessing. A single ring shows the share of doses you have taken, with a clear count of what was taken, skipped, and missed, plus a week at a glance so a slip stands out before it turns into a habit. It is the honest mirror that makes a protocol easy to course-correct. The rest of 2.1.0 is built to back that score up. Your full dose history now lives on a calendar on the Today tab, where you can move month to month and tap any day to see what you took, missed, or skipped. If you would rather scroll a straight timeline, a new list view shows the same history newest first, and you can switch between the two with a single tap. Logging a dose after the fact works the way you would expect, too. The log screen now shows which scheduled dose you are filling, like "Scheduled for Yesterday at 8:00 AM", and a dose you record late counts toward the day it was actually for, so both your history and your adherence stay accurate. Weeks also start on Sunday to match how most calendars read, and every date and time follows your own profile time zone. Also fixed: • The calendar and adherence update the moment you log, skip, or edit a dose • A handful of smaller fixes and under-the-hood polish

Still 100% free Peptide Tracker remains free with no ads, subscriptions, or paywalls. Version 2.0.1 is a round of fixes and polish based on your feedback since 2.0. Injection site rotation now works the way it should. The site you've gone longest without using is highlighted as your suggested next spot on every screen where you log a dose. Reviewing a protocol's dose history is clearer and easier to follow. Creating a new protocol is smoother, with smarter weekday defaults so the schedule starts closer to what you have in mind. Also fixed: • Cleaner account settings • A handful of smaller fixes and refinements

Still 100% free Peptide Tracker remains free with no ads, subscriptions, or paywalls. Version 2.0 includes a cleaner design, a simpler stack setup experience, and a more powerful Calculator.
