What's New in Stackr

3.5.3

August 26, 2026

New peptides, all requested by you: BPC-157/TB-500, Tesamorelin/Ipamorelin, GHK-Cu/KPV, and Lipo-C/B12 blends, plus Cartalax, Alprostadil, VIP, and PNC-27. Dose reminders got a major fix. They now schedule up to two weeks ahead, fire right away if a dose time passed while the app was closed, and no longer get cleared by mistake. Also smoother onboarding animations.

Why the paywalls???

Annoying paywalls, after trying to get into the app keep forcing paywalls, had to delete and reinstall over and over, won’t let you close paywalls literally no x, yall don’t follow TOS. I don’t see any reviews talking about it. Paid reviews? Found app on TikTok and thought it was good. Couldn’t do anything without paywall showing up every millisecond and can’t close it so I have to delete and reinstall. Horrible.

Sub

Honestly sucks that you can’t even test out or see the app before having to pay for a subscription and an especially pricey one at that for what? If the subscription was like a dollar I’d maybe consider but 5 a month for something you could do the same for free on chat gpt is crazy. No free trial or sample experience before having to pay for an app is bogus.

Response from developer

Hey Girlyas, please message us at support@stackrpeptides.com and we can get you subscription to try the app out! We recently introduced free trials and you may have been served the old paywall with no trial. It also costs to develop and maintain the app and invest into marketing so people can discover it, so please keep that in mind.

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.
