User reviews

Multi-Musician

A great tuning it works on all my instruments, including a few that are not shown in emojis good job creating this.
I play music in 49 states multiple cities all through Canada every Providence, multiple cities twice Europe, eight countries multiple cities

Fantastic tuner

It’s honestly worth the few bucks. It works 100% accurate down to the hertz, also has a bunch of different tunings available. Highly recommend, easy to use.

Support needed

My favourite tuner until switching to a new device. Unable to purchase or restore pro features which leaves it almost useless now. Please fix this.

Now you can tune to 432!

I should warn you though… It will be hard to go back to 440. I love free apps, and this one would’ve gotten five stars if I didn’t have to manually touch the screen every time I wanted to tune, a different string.

Great but missing one feature

This app is great, but there is one missing feature that would make it perfect, and that is the be able to make custom tunings. I play a lot of songs that have nonstandard tuning and it is a PAIN to scroll through the entire scale to find each note for all 6 strings. It also stinks because there are tunings I only use for specific songs, and it is a pain to have to memorize the tunings for a single song when I could just make a custom tuning for it if the app had that capability. Please consider adding this function, it seems like a small change that would go a long way.
