### 5/5 — Awesome

*2026-05-10*

Super convenient

### 4/5 — Great unit converter app.

*2026-05-08*

This is a great converter app that is extremely useful for quick conversions, and is very easy to use. It does have a good amount of conversions, but if it had a money converter added it would be perfect. If you want a converter app and don’t need a money converter, I would recommend that you get this. 

It’s great that you only pay once for the app, and it’s not a cash greedy monthly or yearly subscription!

Nautical Miles is the unit used in shipping and aviation worldwide. The converter is incomplete without it.
