### 5/5 — Great companion to my callipers!

*2024-12-23*

I’ve been waiting for a fully fledged calculator for my Bozeera body fat callipers that isn’t a website and is accessible offline for years!

This app does exactly what I need. £10 seems quite steep for what it is but it is well polished and one-off payment instead of a subscription is a nice touch!

### 5/5 — Love it

Exactly what I was looking for. This app has a number of different formulas to choose from and it's very easy to use.

### 5/5 — Nice

*2024-12-21, version 1.4.0*

Cool app, precise and easy to use
