It’s also fantastic for scheduling and logging doses using its calendar feature. **Developer response:** Thank you for your review :) ### 5/5 — Love Love Love *2025-12-27* I love this app so much! So easy to use, contains everything you need & its not all cluttered up!!! I am a forever user!

When I reached out to them and put a review of that effect, they responded within a day. And added the syringe size that was missing for my personal needs. What that tells me is that the level of response from this company is well above what is normally experienced in the industry. So I’m completely deleting and changing my review to this one. Nice work team **Developer response:** Thank you for your feedback :) I note this requests and will be added in a future version of the app Have a great day, Rodrigo ### 5/5 — Highly recommend *2025-04-04* Best app I have found to manage my peptides! No issues and very helpful **Developer response:** Thank you for your review :) ## Most critical reviews (10 lowest-rated) ### 1/5 — Should be free *2026-06-28* No **Developer response:** Thank you for your feedback. As independent developers, working in the app is our main job, and we need to earn enough money with the app to make a living. Thank you for your understanding. Have a good day, Rodrigo ### 1/5 — Just say you charge! *2025-06-21* Can’t do anything without paying. **Developer response:** Thank you for your feedback Have a great day, Rodrigo ### 1/5 — Not enough settin g *2025-05-24* Surprisingly unlimited given the capability of this app. One would think that to create an app that does what this can, you would put settings for all of the commercially available syringes. Also, it’s extremely surprising that you wouldn’t have choices in the dosage size, but rather limited to micrograms. The calculations aren’t that incredibly difficult for the work that has already been done on this app. Sadly, I’m going to look for a different solution than your app. **Developer response:** Thank you for your feedback :) I note this requests and will be added in a future version of the app Have a great day, Rodrigo ### 2/5 — Last Update was Terrible *2026-03-23* The last update doubled all dosing schedules and now even when I log a dose it looks like I still have to take it. You should also be able to change/update a dose without it changing your past schedule. **Developer response:** Hi, thank you for your feedback. We have detected the issue in the update and we are fixing it right now. Apologies for the inconvenience. Rodrigo ### 3/5 — Worked great…til it didn’t *2026-06-27* Subscribed with a 3 day trial. On day 2, everything’s locked, no access to previous pins, etc. Need more stability in a tracker such as this. **Developer response:** Hi, thank you for your review. There was an issue in one of the versions that locked some users out when they still had the trial. That issue is already fixed in the latest version of the app. If you continue having the issue, please text to hi@pepflow.app so I can fix it Have a good day, Rodrigo ### 3/5 — Not able to use on 2 devices!?! *2026-03-02, version 2.2.1* Love the app, paid the 29.99… but why can’t I use it on my iPad and iPhone? I guess because there is no login? Too bad, would not have choose this if I knew that ahead of time. Otherwise would have been 5 stars. ### 4/5 — Need free version *2026-06-13* Never paid for an App and not starting now. Offer a free version to us cheapskates. Looks like the perfect App., but not the perfect price. **Developer response:** Thank you for your feedback. We will take it into account for future versions of the app. Have a great day, Rodrigo ### 4/5 — Nice *2026-05-11* Only thing missing would be calculating specific Peptide person’s weight recommended dosages **Developer response:** Thank you for your feedback :) I note the request and will be added in a future version of the app Have a great day, Rodrigo ### 5/5 — Ich bin sehr zufrieden *2026-08-23* Alles ist sehr übersichtlich funktioniert auf jeden Fall top **Developer response:** Vielen Dank für deine Bewertung :) ### 5/5 — Easy and accurate *2026-06-15* So easy to use, loving it so far **Developer response:** Thank you for your review :) ## Most praised reviews (8 highest-rated) ### 5/5 — So helpful *2026-06-15* This is THE most helpful app on my phone! **Developer response:** Thank you for your review :) ### 5/5 — Must have *2026-05-28* Keeps all Peptide info nicely, organized, and send reminders as well.

The is the only one I’ve used so far this is hitting the mark with my needs. Features and adjustments keep happening and just in the last few weeks even the app has really improved. Multiple schedules per dosage was huge for me and I love being able to track where I have the shot. Easy recommendation. **Developer response:** Thank you for your review :) ### 5/5 — Easy *2026-05-05* Just what I wanted Easy and functional. **Developer response:** Thank you for your review :) ### 5/5 — Great App *2026-04-27* Easy to use and great way to track my peptide protocol **Developer response:** Thank you for your review :) ### 5/5 — Love this Peptide App! *2026-04-15* I needed a peptide app with ALL THE THINGS.

Completely happy, wouldn’t change a thing! Love the calendar, that I can color code, it’s perfect for my needs! **Developer response:** Thank you for your review :) ### 5/5 — The BEST *2026-02-15* I’ve looked at numerous of these apps, but this one is organized so well and allows me to do everything in one app. I just love it.
