Ratings and reviews

Very good tuner. The only problem is that it needs a reset button to put it back to the original calibration in case the user accidentally adjusts it. I Uninstalled it 2x attempting to reset it then finally figured out the I had to make the "adjusted custom value" 440. This meant I had to hit the little adjust button more than 400 times to correct it from the I correct setting of 30.

I just biught a guitar and need a way to tune it, so I tried this app. First off, no ads, no BS, no reminders. Just an app that you can tune with. For the no ads alone I bought the Pro version. However, I don't think I'm using it properly/efficiently and I can't find any documentation, so I'll stumble along as is because it works great and I love the developer's attitude.

Thanks for making a free and ad free tuner app. I appreciate your service. I was amazed that the app lets me calibrate the "A" pitch to and external audio source. This is key for my use as we tune pipe organs onto themselves often - not to some standard. However I can't really use it because we need to be able to calibrate to any of the 12 notes not just "A". That's what the paid app cleartune on iOS lets us do, but they don't make that for Android. Anyways, thanks for all your work regardless!!
