An easy-to-use accurate visual chromatic tuner for your instruments. Best for higher pitch instruments such as the violin, flute, clarinet, trumpet, or oboe, but will also work well using the harmonic frequencies of lower pitch instruments too.

Provides a simple interface to visually check whether the pitch for a note is low or high, and lets you "see" the pitch change as you make adjustments. Tuning has never been easier.

Shows exactly how many cents (1/100ths of a semitone) a note is out-of-tune. This app listens to your instrument. It does NOT play a tone.

- Developed in Austin, Texas, the "Live Music Capital of the World".
- Extremely accurate - within 1 cent (1/100th of a semitone) of each note with sub-second response time.
- Supports transposed tunings for instruments in the key of E-flat, F, B-flat and A
- Adjust pitch incrementally from 400 to 480 Hz or up/down a half/full step from A440. (The International Organization for Standardization specifies the frequency for the note A in the treble stave as 440 Hz. ISO 16:1975)
- Doesnt directly pickup fundamental frequencies below 120 Hz (B2) because of iOS device hardware limitations, but will pickup the harmonic frequencies which will tune more accurately.
- Great for the violin, flute, clarinet, trumpet, or oboe.

Pros and cons of Tuner!! app for iPhone and iPad

Tuner!! app good for

Works fine tuning my flute. Its well designed and easy to use, but theres a bit of a lag when its picking up the note.
Awesome app. Not a musician but sounds very accurate. Easy to use too
This app is great for many instruments. So far Ive used it to tune a violin, guitar, bass guitar, dulcimer, and a trumpet. Totally worth the low cost.
This is really a fantastic app, and is very accurate! Worth the dollar for sure!
Having found the guitar tuner so useful I got this app so I could tune my A string (guitune app worked for all other mandolin strings). It worked like a charm!
I play clarinet in a band and when it came time for tuning I was always sharp or flat. Since downloading this app Ive been much better cause I can see where I need to adjust. Its been a great help. Thanks!!

Some bad moments

I bought this app because I was looking to get a very responsive tuner that could follow the notes while playing my instrument (cello). Since the description claims a sub-second responsiveness, I gave it a try. I own an iPad 3, and it is running at about two frames a second. To catch up from my upper A string to the lower C string, it takes like 5 seconds. I dont know if it is because of the retina display with many more pixels to draw or what, but this app is totally useless now. Please fix it, because it seems otherwise quite promising.
Small file so Ill keep it but there are better ways tune a guitar.
As a professional oboist, I am dependent on a tuner to test my reeds, and to tune before a performance. Before the orchestra begins to play, they must tune. Who do they tune to? That would be me. I need a tuner that is accurate 100%, and I never get that with this application. Whenever I play my A-440, it always registers it as a G that is 24 cents sharp. Even if it had a sustained pitch that I could tune to, that would be infinitely helpful.
I am a flute maker by trade and and I am now using Tuner!! As my main instrument tuner. The read out is very stable and easy to read and very accurate +- 1 cent (100th of a semitone). You cant go wrong with this one. Its a great buy! James Hall - Hall Crystal Flutes
Doesnt work with electric guitar. If you make a paid app, it should work.
This tuner does not correctly identify pitches - it seems to be picking up overtones instead. It is slow, unresponsive, and completely inaccurate.

Usually Tuner!! iOS app used & searched for

trumpet tuner, obie, and other. So, download free Tuner!! .ipa to run this nice iOS application on iPhone and iPad.
