For anyone who has ever been involved in playing a musical instrument, you know the importance of tuning, which is why DaTuner is for you.
DaTuner is a highly accurate strobe tuner that not only automatically locks onto the pitch you're playing, but also tells you the register you're playing in along with how many cents sharp or flat you are. It's a welcome change from the needle-reading we're all accustomed to, and it's as intuitive as it is functional.
DaTuner also boasts a highly functional settings menu that lets you change everything from the sensitivity to the responsiveness, the color for notes that are sharp or flat, and even the temperament, for those who subscribe to the notion of just intonation.
A pitch pipe is also included in DaTuner, for those who prefer to tune to a relative pitch, although it has a tendency to be a little buggier than just tuning using the phone's microphone. Still, it works often enough, and in the event it doesn't, there's still an incredibly powerful tuner at your disposal.
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 gStrings, but DaTuner has proven to be so powerful, easy to use, and accurate, it'd be foolish to not use it.
DaTuner comes in three varities: free, donate (with a few more features), and experimental (for those who want to be on the cutting edge of tuning technology). The donate version is $2.34, but when dedicated tuners cost upwards of $40 or more, this is an absolute steal.
