Usually pretty good

An alpaca

It’s a nice app the whip out quickly to tune. It’s a little challenging to play and watch for intonation while working on a piece of you have the lite version. The ads will pop up covering the whole screen. Sometimes very frequently and times it’ll make you press play so you can get the video started so you can go back to tuning. That’s a little annoying. Also I ran into problems where it will stick onto one note and as play other notes, it’s frozen on that precious note until I exit out the app again.



I used this app to tune my clarinet and when I played a C it said that it was VERY flat (-50) then for the next 10 minutes I kept on trying to get a perfect C and I couldn’t! Then I decided to test this app with my piano, that was tuned shortly ago (a few months ago) I don’t play my piano that much, I play it about 30 minutes a day everyday and it’s in pretty good condition. I played a C on my piano and this app said it was a D!Honestly I don’t know what to say about this app, it works pretty good for others but I don’t understand what happened here! I’m giving this app two stars for actually being able to detect sounds.

Ruined by the ads


I used to love this app because I found it to work well. I would have given it 5 stars. The last time I tried to use it, though, there was an ad at the bottom that automatically expanded to engulf the entire screen with a video clip of a puppy. When I closed the full screen ad, it would pop back open again within a few seconds, rendering the app completely useless. This problem persisted after closing and reopening the app several times. Now I am on the search for another tuning app; a friend of mine uses PitchLab and it seems to work well for her, so I might give that one a try.
