Don’t waste your money. *2026-09-27* Worst peptide app on the AppStore and there’s not even a free trial and it forces you to pay upfront without even trying anything. Do not recommend, check out other peptide apps instead!! ### 1/5 — BILLS U AND WONT REFUND *2026-09-22* I ACCIDENTALLY paid for a yearly subscription. Once I noticed i IMMEDIATELY SAME DAY cancelled it but yet have to receive my MONEY BACK. It’s so frustrating and very upsetting!! ### 5/5 — Great *2026-09-17* Has everything I need to keep track ### 3/5 — Not user friendly *2026-09-17* It’s a great concept, but it’s not easy to use. Once I entered my dose, I could never find where to change it. It wasn’t subtracting my dose from my supply, and it never increased the estimated amount in my system. It also won’t let me log a dose in mg if my supply is entered in units. Has a few things to fix, but I’m sure they’re in the works. ### 5/5 — BEST IN MARKET *2026-09-02* 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 ### 5/5 — Everything in one place *2026-09-02* 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 ### 5/5 — Needed 10000% *2026-08-31* 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. ### 5/5 — Great app *2026-08-26* Love how simple and useful it is. Makes tracking much easier ### 2/5 — Why the paywalls??? *2026-08-24* 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. ### 5/5 — So helpful!! *2026-08-23* Love the features it has! ## Frequently asked questions about Stackr ### What is Peptide Tracker's primary function?
