Ratings and reviews

The app seems good but it's pretty buggy. Unable to contact the devs through the app, nor make feature suggestions because the buttons do not respond. I specifically am looking for box fill calculations. thanks!

have to watch several ads to see results of calcs. Developer made it impossible to skip them by placing skip so close to mute, you hit mute.

the best and fundamental app
