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.

BEST IN MARKET

This has been game changing. No more forgotten doses. No more guessing on when I need to refill my supply. It’s my second brain for when I forget everything

Everything in one place

I downloaded this app planning to just log my doses. Little did I know there are so many functionalities and I check this app multiple times a day for research and calculations. Definitely recommend this app

Needed 10000%

Stackr makes it so much easier to keep track of what I’m taking, doses, and my schedule all in one place. The calculator is super helpful too. Definitely one of those apps I didn’t think I needed until I started using it.

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.
