What Android Central had to say about us:

"For the Android-loving musician, I think DaTuner Pro is easily the best tuner you can have on your device. I used to give that title to *see review!*, but DaTuner has proven to be so powerful, easy to use, and accurate, it'd be foolish to not use it."

DaTuner is for everyone!
With an easy to use interface and a variety of adjustable features, DaTuner is the ultimate tuner for nearly all instruments. Whether you’re a professional musician, or just a beginner starting to learn how to play a new instrument, DaTuner is the app for you!

DaTuner's display is easy to read
Nearest note and octave is displayed in a giant, easy to read font, and frequency in hertz plus error in cents is displayed at the bottom of the screen. Sensitivity is auto-adjusted, but can also be adjusted by touch via a bar on the left-hand side of the screen, and the speed/accuracy of the algorithm and the relative frequency can be adjusted via the configuration menu.

No Dead Zone
There is no "dead zone" with this tuner app as is the case with many other apps. Instead, the whole display turns green when the incoming frequency is within a configurable range of the target frequency and you can still see changes in pitch even in the "in-range" area. Both the "in-tune" range and the colors shown for sharp and flat can be configured.

Not worth five stars? Please ensure to leave a comment with your rating so we can fix it! Thanks!

This app in earlier revisions allowed .e to adjust the A4 reference frequency. I can get in and tell it to change and as soon as I tap the check mark to accept my setting, it instantly reverts back to the default 440Hz frequency. I have never had premium and could change it before. Also the time it takes to load used to be fast, but since the guitar drawing was adding, it takes significantly longer. Time for a different tuning app. This one has been ruined.

Tuner function works well when you can get to it, but it's behind a wall of ads that are intentionally designed so that you can not easily click out of, even after you finish watching. (The "x" is hard to find or so small that you miss click, get taken to the app store, then when you navigate back to the app it plays another ad)

Skip this tuner! I used this app for several years and liked it. The display was large enough, uncluttered and easy to use for quickly tuning up my horn before a gig. Just click on it and start tuning right away. And the banner ads were unobtrusive. Now? The opening splash screen takes too long and then it immediately goes to a long ad before letting me tune. And the pro version? $30 a year? Nah. I'm deleting this in favor of something cleaner and with a reasonable upgrade price.
