This also helped me figure out when I was going to run out! Super helpful ### 5/5 — Best Peptide Tracker *2026-04-26* This is the best peptide tracker available. Use this one not the others ### 5/5 — The only tracking app I actually stick with *2026-04-21* This app makes tracking my vitamins so much more organized and easy to manage. I like that I can track everything in one place without overcomplicating it. It actually makes it easier to stay consistent and feel confident that I’m doing things right. I am also a type one diabetic and I use this to plan when I’ll need to request a refill on my insulin! You can tell a lot of thought went into it. It’s simple, but really effective. Definitely worth it if you want a better way to keep track of everything. ## Frequently asked questions about Stackr ### What is Stackr?

Your notifications follow the same numbers, so a heads-up at 21 days actually says 21 days. Settings › Notifications › Alert thresholds. Reorder heads-up is editable How far ahead you're warned to reorder — 10 days by default — finally has a control. It was doing the work all along with no way to change it. Free for everyone. New name, same app Stackr is a tracker first, so the name says so. The reconstitution calculator isn't going anywhere. ### 1.3.2 — 2026-08-05 • Fixed cloud sync and email sign-in, which had stopped working in the previous release. • Dose accuracy fixes — including cycled items that weren't counting down at all, and items charged for time they spent archived. Settings will tell you if anything on your stack needs a second look. • Honest supply counts — if Stackr couldn't track a stretch of time, it now says so instead of quietly showing a number it can't stand behind. • Subscription reliability — a flaky connection or a payment retry can no longer drop you to the free tier while you're still paying. • Database hardening and a much larger test suite, so this class of bug gets caught before it reaches you. ### 1.3.1 — 2026-07-30 • Export to CSV — Pro members can now export dose history and inventory as a CSV file. Bring it to an appointment or keep your own records. Find it in Settings › Data. • Cloud backup hardening — tightened security around cloud sync so your data is locked to your account at the database level. • Promo codes fixed — redeeming a promo code works again. • Corrected the version number shown in Settings. ### 1.3 — 2026-04-19 What's new in 1.3: - Fixed dose tracking math for vial-based supplements (TRT, GLP-1s, peptides) — supply now decrements accurately - Rate Stackr button now opens the App Store reliably - Titration schedules save properly - Settings show when cloud-synced items exceed the free plan - Faster boot, smarter sync, and various reliability fixes ### 1.1 — 2026-04-17 No release notes. ## Related topics [doesly](https://appshunter.io/ios/topics/doesly) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
