Sehr gute tuning app. Ohne schnick schnack oder werbung. Tut was sie soll. Benutze sie für die Gitarre seit mehreren Jahren und hatte nie Probleme.

The best tuner for musicians

I experiment with instruments where tuning is an issue: cello, winds, etc. This app is very pleasant to keep open while playing: it looks great, and because of the design I can keep an eye on my pitch while keeping it in the periphery of my vision. There’s enough customization to make it super useful, like dialing in the precision. Pretty, and useful.
