### 1/5 — Freezes phone

*2025-10-20*

Slowly phone to a crawl and app graphics stop working. Couldn’t even do my first calculation - Regretful purchase.

### 5/5 — Great app!

*2026-02-06*

App is working great so far.  Helps me calculate dosage and also helps me keep track of the doses I’m taking.  I like that you can also add custom doses for peptides not listed.

### 5/5 — MORE Than A Calculator!

*2026-02-03*

This is the Swiss-knife of peptide apps! 

Calculator: ✅

Vial Tracker: ✅

Inject Logger: ✅

Dose Reminders: ✅

On top of a clean, super easy to navigate interface. Must have for research goers!

### 5/5 — Great dosage calculator

*2026-02-03*

Great way to calculate and remember dosing for research. You can select the peptide in a menu, may I recommend the dev to go ahead and show a standard range for each peptide? To prevent bad miscalculations.

### 5/5 — Just what I was looking for :)

*2026-02-02*

It does exactly what it says. Very easy to use!

### 5/5 — Amazing

*2025-10-21*

This makes calculating my peptides really easy.

### 5/5 — Super helpful and accurate

*2025-10-18*

Super easy to use and accurate.  History valuable for next time you reconstitute your vials.  Allows you to add new Custom Peptide names not already in library.

### 5/5 — Amazing

Super useful in figuring out the proper dosages!

### 5/5 — Easy to use!
