InTune began as a way for researchers to test pitch discrimination, the ability to differentiate pitches that are close together. But then researchers discovered that musicians improved the more often they played – 3x faster than those who didn’t. Download for free and see if InTune works for you!

A great app

This app could is helping me to be better at pitch. I liked the version previous better. In the previous version once you set a sound, it stayed on that sound the next time you opened the app. This version asks for your choice of sound between games whether you keep the app open or restart it. The old version had a chart that shows you where your score puts you on a spectrum of users. The new app tells you where in the spectrum your score is on the spectrum. Overall it runs a tad slower.
Still it’s super valuable!

Oboe timbre inconsistent

Overall I think this is a great app and I love using it. The addition of the new timbre choices at a rather reasonable $0.99 is a nice touch. However, the oboe option is broken, and the flat oboe sound is qualitatively different from the sharp oboe sound which makes practicing on that choice trivially easy. The English horn option somehow doesn’t have this issue; if I memorize exactly how the vibrato behaves in the flat vs sharp versions i could use that to hack the game but it’s something I can choose to ignore. I haven’t tried any of the other options but I recommend looking into them to make sure that the only thing differing is the pitch and not the tone quality/behavior; even if those differences are subtle people are bound to pick up on them.

Developer Response ,

Thanks for the feedback. We redid all the instrument sounds for InTune 5.0. Would you email us at to let us know if the oboe sounds better now?

Great to use in the classroom

As a middle school band director, teaching students to have an ear for intonation and tuning is important. My students love to use the app as a game - the contest is to see which class can score the highest. I love to see them have fun while learning to develop an ear for intonation. Their only concern, so also mine, is the tone generation can be somewhat uncomfortable when the whole class is listening. The team that has created this app should be commended for bringing such a great app to the public, and should make more!
