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!

Must Have App

I remember this app from back in the day. I redownloaded recently and I’m very happy to see the expanded range of notes to hear, and the variety of instruments. This app is a fun way to test and improve your ear, and I highly recommend for anyone who wants to fine tune their ears.

My only complain is that some of the timpani sounds could be improved. The higher notes sound fine, but the low notes have so much impact and thud that it makes it really hard to hear the actual tone and pitch of the drum. Those low notes sound more like a bass drum than they do timpani. I think it would be beneficial if the timpani notes were played with a much softer mallet, as well as a lighter touch. That would create a more characteristic sound that mimics how a timpanist would actually play the drum.

I hope I can see that improved as that’s the only thing holding back my rating from 4 stars to 5. Again though, very useful app and definitely worth being on any musicians phone.

Please add a way to replay the pitches

I use this for tuning practice and highly recommend it. The old version was better in my opinion, but I still like this version. I like that the pitches are not played as fast with this new version, but I liked the scoring with the old version.

I would love it if there were a way to hear the pitches played again. Sometimes a second listen is needed to make sure your brain is thinking correctly. Neither the first or second version has offered this. I figured that would be among the list of improvements foe sure.

Also maybe something telling you where your problem areas are… which octaves… and those could be used to drill down even further.
