Tuner Lite

I am a severely vision impaired person. I am able to magnify the screen of my phone with a special camera so that I can see A huge Lee magnified image of my iPhone screen and see the needle on tuner lite. That being said, none of the buttons of this app will work when voiceover accessibility feature is activated on the iPhone. As many vision impaired musicians as there are out there, the developers of this app should have made it accessible to those of us who want to use an electronic tuner for our instruments but need voiceover to tell us The function of each button we are activating on the screen and function correctly with the usual voiceover gestures needed for other features on the iPhone As usual, we vision impaired people are left out again when it comes to app development. This app needs to be accessible to everyone. I personally am very tired of talking to app developers about the fact that we need equal access and being told that when the ads they put in the App Store were developed, they were not meant to be used by blind people. This is really no longer acceptible. If Apple can include accessibility features on their product. App developers can make sure that their products are 100% accessible to all.

Usually pretty good

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.
