5 years later. still using it. I like it has a lot of flexibility and I can hear the pitch, not just see it. I'm old fashioned and I can tune faster and better to a tone than a meter.

I found this because I have an old tablet that wouldn't run the Fender tuner I had been using on this phone. Honestly it quickly became my favorite, and in the best one here - at least that I tried. If I had the money to blow on apps I'd buy the pro version just because even though it does what I need it to do for free. In fact I'll probably buy when I can anyway.

Simple, easy to use, low storage consumer, tone accurate, no annoying adds, more importantly you can still do so much on its free version. It's actually better than the top searches tuning app I have used (and uninstalled) before this. By far the best tuning app for me. Now I can tune my yamaha fife and LingTing kalimba in peace
