### 1/5 — Was good app

*2017-10-18, version 1.0.5*

Still doesn’t work with iOS 11. Hangs up and leaves keyboard on screen.

### 5/5 — Awesome app

*2017-10-06, version 1.0.4*

Please update it to work on iOS 11

### 3/5 — This is NOT for turning applications

*2014-11-05, version 1.0.4*

The app only supports data that is used in milling. It DOES NOT produce any turning data. Decent app for milling, but there is no option for imperial or metric measurement.
