DaTuner (Lite) is an all-purpose, precise and responsive chromatic tuner app for Android with a simple interface. Rather than focusing on fancy graphics assets, we made it fast and easy to use!
** HERE BE DRAGONS: This app is completely FREE and AD-FREE. If you've never tried DaTuner, and like leaving 1,2, or 3 stars without a comment, please try one of the other free, ad-supported tuners instead, because this app is terrible, awful, no-good, really, really bad!, I'll just tell you that up front so you don't bother! :)**
For the rest of you, DaTuner is super precise from A0 all the way up. For even more accuracy, see the real, multiple-harmonic strobe tuner on the Pro version, reviewed by Android Central:
"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."
Extremely fast, with latencies and averaging all adjustable via the settings menu. If it's fast on 5 year old Android devices running 2.1 without fixed-point support, then it is GUARANTEED to be fast on your device! :)
DaTuner converts the fundamental frequency to the nearest note and error in cents for quick and easy tuning of your guitar, ukelele, violin, bass, cello, mandolin, piano, harp, saxophone, Ducati timing belt, harmonica, kazoo, you name it.
DaTuner's display is easy to read; nearest note and octave is displayed in a giant, easy to read font in the center of the screen, 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 (if other than 440Hz) can be adjusted via the configuration menu.
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 small changes in pitch even within the "in-range" area. Both the "in-tune" range and the colours shown for sharp and flat can be configured in this version.
Screen and filter lock allow you to select the note that you would like to tune to, with filter lock ignoring anything outside of the range of the note you wish to tune, which is useful for tuning in noisy environs.
1.) No dead zone - screen changes to green when tuning is good.
2.) Auto-Sensitivity - no configuration required.
3.) Bright, easy-to-read display.
4.) Quick, accurate and precise.
5.) Screen lock: Lock to the note you want to tune, even if extremely out of tune and make your way up/down to it.
6.) Filter lock: Lock and filter to a specific note and filter out everything outside that note's range.
8.) Reference frequency adjustment for orchestra tuning, adjustable manually or by letting the app listen to another reference.
9.) Some instruments can be selected - more to come!
10.) Choice of colors for sharp/flat/in-tune
11.) Sample rate range 8kHz - 48kHz.
Features in the PRO version [not in this free version]
1.) [PRO] REAL strobe tuner display, with up to 4 overtones!
2.) [PRO] Transposition.
3.) [PRO] Temperaments. You can modify the ones that exist or add your own using a text editor. The temperaments are saved on your external memory under the /DaTuner directory.
4.) [PRO] Notation (ie Solfége, English, English sharp, English flat, Northern European.) Customization of these will be possible in a future upgrade.
5.) [PRO] Pitch pipe with multiple harmonics, so it is audible even when playing low tones.
6.) [PRO] Accelerated tuning algorithm.
Not worth five stars? Please ensure to leave a comment with your rating so I can fix it! Thanks!
