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!

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.

Great for classroom use too!

As a middle school band director I use this app to help my students start listening more carefully to fine differences in pitch. It’s very easy to understand and I like the binary choice between higher and lower. Since it resets each time to easier levels, the kids who got lost when we made it to the really fine distinctions are able to rejoin us. InTune really helps them start paying closer attention to pitch.
