Very good no nonsense tuner (many android tuner apps are essentially spyware needing absurd permission and 100s of cookies), but I trust this as an app doing the job it is meant to do. A couple of areas it is not quite the best: 1. The display is cramped and hard to read on a phone, yet there is lots of unused space. 2. Background noise can confuse it. I realise this is impossible to fully solve, but not quite as good at noise rejection than previous tuner I used But overall I am very pleased.

Works for a few hours, then stops responding. I upgraded to this for the stretching feature, and it was working fine until the app decided to stop measuring the frequency. I tried clearing the cache, clear all data, relaunching the app and nothing works.

Fantastic app. It's a tight tuner for my piano or guitar, and it's also great to find out what key something is in. Try it out, and you'll realize that paying to go ad-free is a no-brainer. Last tuner app you'll ever need.
