About this app

Tune your piano by a new method based on entropy minimization, which
takes the individual characteristics of your instrument into account.

The tuning is carried out in three steps:

- Record all keys of your piano.
- Compute the optimal tuning automatically.
- Use the integrated tuner to tune your piano.

IMPORTANT NOTICE:
Piano tuning requires sophisticated skills. Please read the remarks on
the help pages before starting.

The performance of this app depends on the quality of your device's microphone. I'm so grateful for the hard research that went into the theory, and development to turn it into a fully functional (and open source!) program. I've turned my piano effortlessly, and agree with the suggested deviations. To all the entitled reviewers who dislike this, feel free to download the source code and improve it rather than complain 😁

The app works wonderfully. With this and a piano frequency chart I was able to make my wife's old piano sound so wonderful it will make you cry. A couple of tips: Read the instructions! Whether you use the in app help or download the manual off the website read them! You won't get this app to work otherwise. And make sure to save your initial analysis of your piano. Doing so will make things go a lot faster if you need to pause midway tuning or tune again at a later date.

Amazing piece of science! I set out to tackle the tuning of a newly acquired used piano. 15 years old, well taken care of, but never tuned. This app brought me up over 1/2 note to concert pitch and was nearly perfect. I'm going to allow the piano to rest a couple days before repeating the process for a finished tune. It sounds so good already!
