DaTuner PRO is an, all-purpose, precise and responsive chromatic tuner app for android with a simple interface.**If you've never tried DaTuner and like leaving less than 4 stars without a comment, please save your money; this app is terrible! :)**For the rest of you, DaTuner is one of the smallest tuners on the market clocking in at ~ 800kB!Super precise from A0 all the way up to > C8! The multi-harmonic strobe functionality in Pro gives almost immeasurable precision all the way down to the lowe
st notes, and is intuitive and readable.Extremely fast, with latencies and averaging all adjustable via the settings menu. If it's fast on 5 year old Android devices running Android 2.1 without fixed-point support, then it will be fast on your device! :)The PRO version also features an accurate pitch pipe and and was 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."http://www.androidcentral.com/android-app-review-tuner-datuner-proDaTuner 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.Features: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.7.) Ad-free!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-tune11.) Sample rate range 8kHz - 48kHz.12.) Transposition.13.) 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.14.) Notation (ie Solfége, English, English sharp, English flat, Northern European.)15.) REAL strobe tuner display, with up to 4 overtones!16.) Pitch pipe with multiple overtones, so it is audible even when playing low tones.17.) Custom instruments/temperaments/tunings via a .xml file.This strobe tuner is not like some others around that "emulate" "virtual wheels and flash lamps." Why use 100 year old technology - the Strobe in DaTuner is based on a modern DSP algorithm and is just as accurate as an old strobe tuner but is easier to read.Not worth five stars?
