What's New in Stackr

3.6.2

October 26, 2026

The calculator is paused. Apple has asked developers to remove all peptide reconstitution calculators, which affects every peptide tracking app. We think this is unreasonable and are doing our best to bring it back. Until then, use the same calculator at getstackr.app/reconstitution-calculator. Also: Active levels now count doses logged in units or mg the same way, and Food shows fiber, sugar and sodium totals.

Does not keep track correctly

I thought this would keep track for me but it does not and I try to update my weight and it puts it as my starting weight so what’s the point to even use this app

The app is great, especially as I start my GlP1 journey.

Favorite app

I’ve tried a bunch of pep tracking apps and this one is my favorite. It’s simple and to the point while still having a ton of cool feature. Love that I can track my food too. Easy 10/10

Terrible

There’s not even a full calendar on this app. It’s very hard to keep track of what you’re doing

FAQ

What is Peptide Tracker's primary function?

Peptide Tracker offers reminders that can be set according to your specific dosing schedule, including daily, every other day, weekly, or custom intervals. Home-screen widgets are also available to show what dose is due next without needing to open the app.

What kind of educational content does Peptide Tracker provide?

The app includes reference pages for commonly tracked compounds like semaglutide, tirzepatide, and BPC-157. These pages offer general education on typical dosing, half-life, route, and mechanism, but are strictly for informational purposes and not medical advice.
