I don’t have to worry or keep anything in my head now. Plus the calculator is free as well but honestly the yearly sub is super worth it. ### 5/5 — Best tracker I’ve tried *2026-05-31* Super convenient design. I love that it’s so clean. Obv makes tracking 100x easier. Would recommend to any peptide user 🔥 ### 5/5 — Great app *2026-05-13* Love it. Makes it easy to keep track of your stack. ## Most critical reviews (10 lowest-rated) ### 1/5 — Scam *2026-08-22* Got billed when was supposed to be free trial ### 1/5 — Sub *2026-08-21* 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. **Developer response:** 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. ### 1/5 — Not worth it. Waste of money. *2026-08-12* I just downloaded the app I saw good things about being able to log my doses and schedule. I am new to injecting and thought this would be an amazing app for a beginner. NOPE. DONT WASTE YOUR MONEY. JUST USE YOUR NOTES APP AND GOOGLE SAVE $20 There are so many bugs verbiage is not good. It’s difficult to log multiple peptides and it doesn’t even tell you what’s wrong or why you can’t. If you mess up on a dose oh well you can’t go back and fix it. I was stupid to pay for a subscription for this. and want my money back. I’ve spent about 2 hours in this app trying to figure it out. It doesn’t teach out anything you’re better off just logging it in your notes app on your phone. ChatGPT was more beneficial than this app. all of the information your paying money for can very easily be found with a google search. for $20 I was expecting it to give me information on my peptides, help me understand the configurations better, and understand the conversions. if anything it made it more confusing. **Developer response:** Sorry you had a bad experience with the app. I’d genuinely like to understand what felt confusing or wasn’t useful for you. If you’re open to it, email us at support@stackrpeptides.com and I’d be happy to chat with you directly and hear your feedback. ### 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. ### 4/5 — Tracking *2026-07-26* So far so gooof **Developer response:** Hey! Thank you for the review. We would love to know what we can update to make it to 5 stars ⭐️ ### 5/5 — Great app *2026-08-26* Love how simple and useful it is. Makes tracking much easier ### 5/5 — So helpful!! *2026-08-23* Love the features it has! ### 5/5 — Love the app! *2026-08-16* I love this app. It makes it so easy for me to track my peps & I love that I have the reminder when I am running low. The library is a huge plus too! ### 5/5 — Must have!!! *2026-08-16* Love the free reconstitution calculator and library!! I wish I would have had this app before I began my peptide journey - it would have helped SO much! At least I have it now and will never try to track without it again ### 5/5 — Life Changing! *2026-08-10* I’ve lost 75lbs due to how well I’ve been able to follow my protocol.

You can easily find out how many units to use and get proper dosing! In the beginning this is so important! The library, tracking and other features are great as well. Can’t wait to see where the app goes and the community it builds! **Developer response:** Thank you for the kind words! It means a lot. We’re just getting started and can’t wait to keep building the best peptide tracker for the community 🚀 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
