Been usingtge free version of this app for 4+ years now. It will have one popup add when opened to use which is no bother at all. The app has the tuning for every string I need, and is very easy to use. I've tried other apps for tuning my string instruments but have always come back to this one 5 stars for me.
Have no idea what everyone is complaining about. This little chromatic tuner does exactly what it's supposed to do. Record the desired note accurately and detects # and b at the same time without switching back and forth. I like it so much, I'd pay for it if I could. Best one I've found.
Finally found a no-nonsense app to help me tune a specialty 16 string instrument I had bought long ago. App based tuners' auto detect is always pretty rough, but this is the best I have found outside of pure guitar ones. Good job developers, lots of love.
For a tuning app, it does what it needs to. Ads are annoying, but what do you expect from a free app? Glad I found it, and while I DID test it on a guitar, it looks like it'd work nicely for tuning my trumpet or piano as well.
i tuned a piano with it and it stable across the whole range, the needle tracks just at the right speed to allow one to tune and to not get confused by harmonics. the ads are tolerable. a great app for sure
Used this to tune my lyre, guitar, and check pitch for singing. I've also used it to listen to a song and it tells you what notes they are playing. 0 complaints
