It’s a great app with a cool looking UI. So far I haven’t seen any adds, but on apps like these it’s bound to happen. I hope not though as adds really clutter up the screen and take away from the minimalistic look of this app. Other than that, tuner is pretty good and has all the functionality you need as a beginner to advanced musician. I wouldn’t recommend this tuner to soloists but for everyone else it’s great.

The tuner is a great app, it tunes trumpets well. Why I'm giving it a 3 stars instead of a 5, is that the watch app only acts as an "external display" for the tuner. I found this out when I tried tuning my instrument when my phone was away, and when I brought it closer and turned on the display, you can see that the app is using your phone. A bit disappointing, but still a good app.

Downloaded this to use for an a cappella duet. Love that I can set the frequency (for $2 upgrade that's still a cheap pitch pipe) since we wanted to try 432. We can also watch the app as we sing to see if we're going flat. So helpful! And the simplicity is perfect.

I am very well impressed about the quality if this amazing app. It is incredible accurate and it manages the sound frequencies till it be the right pitch. I am surprised it be free for such an outstanding app!
