### 1/5 — Cannot edit!

*2026-07-06, version 2.24*

First you can only have 1 dosage you cannot have mcg and mg. So if you have more than 1 peptide with different dosages you’ll have to look up the other ones. I wanted to add notes but I couldn’t save it. I wish I hadn’t paid for this now I have to keep information somewhere else.

### 5/5 — I want to love it

*2026-01-21, version 2.18*

I want to love the app for all the features it has but have run into so many bugs trying to set it up.

### 4/5 — Great but room for improvement

*2026-01-03, version 2.15*

So far, the most practical and useful app I’ve found. However, its frequently laggy, which is frustrating

### 5/5 — Love it

*2025-12-15, version 2.13*

I started using the app to track peptides. If you are tired of tracking everything manually in a note book then this app is for you. Track purchases, dilutions and even custom mixes.

### 5/5 — Committed to excellence

*2025-12-07, version 2.12*

I rarely write reviews on apps for the App Store, but I feel compelled to do so because of the Developer’s commitment to advancing this great app. It’s well thought out, organized and the incredible response by the Developer is unlike anything I’ve encountered.  It’s a great app for me keeping my active plans, inventories, reconstructions / dilutions all organized in one place! It tracks progress towards my goals, reminds me of dosing and takes all of the pen and paper tracking sheets out of the equation. I can even manage my wife’s plans through the new Profiles feature. 5-star app, 5-star vision and 5-star developer!

### 1/5 — Another app that doesn’t work

*2025-11-19, version 2.10*

Wish I had not wasted my time and money trying it. Nobody seems to be able to make a good pep app. I will stick to old school tablet this is too annoying. It’s currently stuck in a screen and can’t even do anything. Not worth the headache

### 5/5 — I love this app

*2025-11-09, version 2.8*

This app is amazing. Yes there are bugs occasionally but the developer is amazing and fixes them basically as soon as they can. Very nice user interface and features.

### 1/5 — Ugh don’t bother

*2025-11-04*

I could not even get through the first few steps to get to adding stuff. Gets stuck on a page and you can’t get out of it. Had to restart phone multiple times just to try and get through their next steps but no such luck. Looked promising but it’s a major dud. Luckily I didn’t waste a lot of time on it since I could not even get to the part to enter all of my stuff. Will try another one…

**Developer response:** Sorry, but I just tested everything on iPhone and iPad. You cannot get stuck anywhere as far as I can tell. And from the signups I can see that it works for other users as well.

If there actually is a bug that I cannot find, please let me know! You can contact me at j.grundherr@pm.me. In the past lots of people asked for new features there that I always implemented rather quickly, I do that for every single customer.

### 5/5 — Jay C

*2025-11-02, version 2.7*

Awesome app helps keep me on schedule for injections and inventory

### 5/5 — This app and its developer are amazing

*2025-10-22, version 2.6*

This app has simplified my tracking process. The inventory management and dose tracking give me a single app where I can track everything instead of the complicated spreadsheet I was using previously. I had a few suggestions for the developer and he reached out for more details and changes were made to the app very quickly. I cannot recommend this app enough.
