Still the absolute best, period!

I’ve been playing guitar for about 20 years. Rock, jazz, blues, some country. I actually started playing classical guitar. Needless to say, I’ve used many tuners. BOSS, Korg, Peterson Strobostomp on my pedalboard, you name it I’ve probably owned it at one point. On my iPhone I’ve tried SO many tuner apps, paid and free, I can’t even count how many. The truth is (and any player who’s worth their salt will tell you the same) that none of them are any good. They’re not accurate and don’t track well. Until now that is! Seriously, this is the app I’ve been waiting for. It’s not only better than any app I’ve used, but it’s also way better than my expensive hardware tuners. AND has a ton of crazy features. Nothing comes close, just get it.

No support

I purchased this product (full upgraded Pro version) because of the high ratings. I can only assume these are fabricated since there is no online manual, no community website for sharing tips or use strategies and my email request for help has never been responded to. The app suggests tuning support for over a hundred instruments, yet I do not see piano or harpsichord. Willing to admit I may be incorrectly using app, but without any means of support, I am in the dark. I do not recommend.

Hello! 👋 Please reach out to us at, we're looking forward to hearing from you! VITALtuner is the highest quality tuner on the App Store in our humble opinion. It beats very expensive hardware tuners in accuracy as well, which we've tested against extensively. We put a lot of research into our Temperaments feature, and VITALtuner comes with the most comprehensive list of temperaments you will find anywhere, over 120. These are all applicable to piano and harpsichord. To find them launch VITALtuner, go to Settings, Temperaments and select one from the categories of Pythagorean, Just, Meantone, Well and Quasi-Equal. You can create your own custom Offsets as well. VITALtuner also provides tuning assistance for stringed and wind instruments by showing you guide notes for 130 standard and alternate tunings spanning 40 instruments. There are many more useful features we hope you will explore! Thanks for buying, and we look forward to hearing from you.
