### 4/5 — Great app

*2022-06-09*

I paid for the ad-free version almost straight away. This app is exactly what I wanted. Similar in look to the iOS version, but with much better accuracy with decimal display.

It would be great to have an option to reset calibration. I accidentally set the calibration by pressing the calibrate button, and now I want to reset it but can’t, hence only 4 stars. If there were a reset option this would easily be a 5 star app.
