I use it to figure out the rhythm of the songs I need to sing for choir and it is just perfect! I can't just look at a page and use a metronome to find the rhythm- believe me I've tried! This app finds the rhythm for me, and I think I'm even getting a little better at recognizing rhythm on my own too. :) Well worth the $3.

This app has saved me a couple of times. I'm never stuck on rhythms anymore. Essential for anyone who plays a musical instrument.

Same layout as the ios calculator, exactly what I was after.

The app is great. This is making my theory homework a hundred times easier.

I love this app! Very helpful!

There are very few things a musician needs, even fewer exist outside mind & heart. This little calculator is one of them; this is one of my requirements. It is mandatory for my students and cannot be recommended enough to everyone else. Best of the best...truly a masterwerk of simplicity & genius.

Amazing app. This app has helped me so much!
