I often use this to measure temperament used by historic instruments or performances. There is a problem that the reference 440 jumps around so leading to inaccurate assessment of the temperament. If that could be fixed this function would be amazing. It's uniquely comprehensive and brilliant. It would also be great to include Kellner in the temperament options.

Please, keep the screen on... This is a wonderful app for working on my tone. But it doesn't keep the screen on, and there isn't even an option to. Pretty, pretty please? Update: my requested feature is in! It works great and Suddenly the app is useful for an entire practice session! Thank you so much!

Thank you for your suggestion that could be a feature in the next updates already! At the moment the best option for you might be to change your Android's standby setting. Update: Please check the newest update: There's a new setting that can keep your screen on while using the app.

This App is superb. I use it for Pipe-Organs. I do not know if the developers are interested in upgrading with features for my kind of instrument. It would be great if it would be able to use data from a temperature and humidity sensor to automatically adjust the pitch for temperature changes. Also the ability to set the ranks of a mixture into the app to help tune all ranks at once as they are always in clean intervals that are always harder to obtain with 3 or 4 pipes sounding at the same time
