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 is the best tuner app on the market. It's very accurate, easy to use, and highly customizable. The ads have been made less intrusive since they were added, but I still cannot bring myself to give this app a full 5 stars after putting me through 60 second video ads on startup that made me uninstall and only reinstall over a year later. Being presented with an unskippable ad while trying to tune tympani during rehearsal is nothing less than insulting.

If you can get to the app, the tuner will help you tune your instrument. The ad system is absolute cancer. There is no coherent intelligible way to close the ad. Basically you're forced to click the ad and then exit out of whatever bullcrap is opened, before you can navigate back to the app, close the ad, and continue to the tuner. I'm uninstalling. Treat us better.

[UPDATE 2: Now it takes about 30-90 seconds to launch, and serving full-screen ads. Can't close the ad so I can tune, for 60 seconds. I'm not going to watch a commercial or play a mini-game every time, before I tune. And $30 PER YEAR for the ad-free version? No way it's worth that! It's time to break up. Uninstalled... monetize *that*.] Was nice, did exactly what was needed.
