Simple, easy to use, and clear. My only complaint was that it only offered up to 1" taps, however the dev was quick to respond to my review and updated the app within a few days to have larger taps! Thanks!

Edit: The ANSI Inch database has been updated in the latest release to include options for up to 1-3/4" taps. I'll continue expanding both the ANSI Inch and ISO Metric databases to include more options in future updates. Thanks for the feedback and review!

Used to be more stars, but since updating to a Galaxy S22 Ultra, (Android 12) it no longer works. It works on an older phone running Android 10. App keeps crashing and will not open.

From what I am seeing this great for hobbies, and a backup to confirm if your brain failed you. Will have better opinion when used for a while.
