### 1/5 — Inconsistent frequency measurement

*2024-12-01*

When I bought this, it looked like the ideal not-quite-pro ETD. After using it for quite a while, I’ve become extremely frustrated by it. It seems to produce a good tuning curve based on the individual piano’s inharmonicity, but I now realize even that is suspect. The issue is that when you measure the frequency of a single string, the ultimate frequency reading varies from token to token by several cents. Which reading is correct? The unison mode could be great, but the app will report all strings in a trichord to be EXACTLY the same frequency, but it says beats are present—my well-trained ears confirm it as pure. I’ve communicated with the developer, who says the issue is with the instrument, not the app, but it does the same thing regardless of whether I’m tuning a Yamaha, Steinway, or Bechstein. There must be better options.

### 1/5 — Great Idea, Useless App

*2019-12-20*

We own a late model Yamaha Grand Piano. From the piano we entered the model , serial number and date of manufacture AND confirmed this information with Yamaha. The data base has no ability to tune this piano. Guess Yamaha Grand Piano’s are too obscure for this App to have it in their database. Useless App!

**Developer response:** You used the app in error. The app allows you to store piano information so that you can provide your customers with better services. This function is not used to contact piano manufacturers.
