String Tuner is the first chromatic tuner that especially designed and optimized for string instruments as: Violin, Viola, Cello and Double bass. Reference sound/Tone generator is provided to help you tune by ear. Moreover, with the optimized algorithms up to ±0.1cent precise , it helps you to do fine tuning quickly with the Built-in or external microphone on your iOS Devices.
Most chromatic tuner used 12TET(twelve-tone equal temperament), but the string instruments as violin usually tune as PERFECT FIFTHS against each string. That's why the default temperament of String Tuner is setted to Pythagorean Tuning. You can still customize to 12TET or Standard Just Intonation when needed.
String Tuner also supports adjustable calibration A4, you can either adjust it manually or using auto-detecting, it is really helpful when your string instrument need to tune based on Piano's pitch(for example). Hit the A4 key of the piano and String Tuner will take care of the rest.

"SO great, way better than that 20$ tuner I bought at the music store that did not even work that well."
"It just works! By FAR the best String Tuner on the App Store! Great UI, just great everything!"
"By far, one of the easiest to use tuning apps. The support of the whole family of string instruments in one app is very much appreciated and makes this app that much more useful for orchestra players"
"just perfect!! easy, simple and clean!"
"I used this app for the first time to tune a children's string ensemble. 4 violins, 2 violas and 2 celli tuned and ready to play in under 5 minutes!!! I could not believe how wonderfully in tune they sounded! Totally recommend it especially if you have lots of strings to tune and very little time."
Thanks, everyone. We will keep making the best music APPs for you.
We have fixed some bugs and made optimization in the 1.3 version:
1. Added four useful tones to help you tune by ear
2. Remember the last tone you've ever selected.
Thanks to everyone, we'll keep improving String Tuner for you!
Ratings and Reviews
Great Accurate App
This is a wonderful app. We currently use it for tuning violins. We like this tuner over others because it lights up green when the string is tuned correctly. Other tuners and apps are very jumpy and use a needle, which we found difficult to use. The is very user friendly and intuitive. Even our six year old can tune her own violin (while she also learns to tune by ear). Can't beat the price and works great!
Did not work.
A couple nights ago I started playing my violin and realized it was out of tune. I downloaded and bought a few apps but this one seemed the best. I tuned for over an hour that night, trying to make the note light but green. when they finally did light up green I was satisfied. however, this morning when my teacher came over to give me my lesson and started to tune my violin with a Snark tuner, my violin was completely out of tune. the G string was flat, the D string was a C and the A and E strings were both sharp. I do not recommend this app. it costs $5 and does not work properly at all.
Out of tune
I was really excited to go and practice my cello but as soon as I started playing it I realized it was out of tune. I didn't have my regular tuner with me so I decided to but a cello tuner app. I had choosen this one because it look easy to use, it was but as soon as I used it and played a song all the strings were worse than before, I tried it on my viola and when my viola was in tune the app said it wasn't. I have a performance for a project with my viola and now it's out of tune. Please do not download this app.
With Family Sharing set up, up to six family members can use this app.
