Not worth the money

I paid $2 for this app after my friend recommending it to me. My microphone is halfway broken, it works with some apps but not others, so when the app couldn’t recognize that I was playing, I wasn’t surprised.
Since I had paid money for theirs app, I decided to restart my phone, and then it worked perfectly! I have to restart my phone every time I want to tune my violin, which is time consuming and annoying.
I don’t think my phone is the problem, because the app works perfectly after I restart my phone. I really like the way this app works, but if I always have to restart my phone, I think I’m going to have to use a different app.

Good but major un-functional low side of piano

This app is great, it is very very accurate with my piano but sadly the tuner cannot track anything lower than A2 of my piano. A little bit too for the high notes you only get to see like 1.5 secs of how much is out of tuned so you can’t really see it for sure. All I need out of all this is the A2 and lower fixed pls. I would pay if this is on the paid app. Plz fix and I will consider upgrading.

Thank you for the review. Please check our other app, Bass Tuner BT1 that is optimised for tuning low frequencies.

Good app, does what it is supposed to

There are buttons to press that will play a pitch for you to match, you do have to hold them down, which might be difficult if you are playing an instrument. It also uses the microphone to pick up sounds and match them to a pitch and tell you if they are too high/low. It work perfectly for what I am trying to do. Good app.
