The app can calculate where to cut in order to get the offset that you entered in the app.
When you need to make an offset you no longer need to guess where to cut, you can simply open the app and enter the data.
You can decide the angle and where your offset should be.
If your offset is not physically possible, then the app will tell you.
The app doesn't require an internet connection.
There is a demo version and a full version.
In the demo version, you can try the app for 3 calculations,
when the tries are up, you can then buy the full app.
This app can only run in landscape mode.
It supports all devices with a screen size of 3.7" and above.
