>>> Extremely Accurate ChromaticTuner

Colored tuning bars guide you quickly and clearly. High accuracy (up to ±1/1000 of a semitone, or ±0.1 cent precise).

>>> Precision Metronome

The metronome benefits from EUMLAB's Real-Time Playback technology. It is extremely precise (±20μs).

Input the time signature you need. Up to 14 metronome tones create your rhythm and the 12 built-in strumming patterns will teach you how to play along easily.

>>> Chord Camp Premium Plan

Chord Camp constitutes the easiest way to create playable Chord Sets. Build simple or complex chord progressions using combinations of chords, then slot them over a strumming pattern and time signature to hear how it sounds. By further combining chord progressions, one can effectively build entire songs! With our prized Chordec technology, you can even extract chords and key signature from the original audio and Microphone! You can transpose song's key without altering the tempo, or conversely slow down the audio without changing the pitch!

>>> Scales

Scales are important for any guitarist. They are often central to different music styles and provide a roadmap for improvised solo and melody composition.

Our app contains 108 different scales, ranging from common Blues and Major/Minor scales to wacky Byzantine and Arabian scales!

>>> Interactive Guitar Chords

The chord tabs contain thousands of chords such as Major, Minor, 6, 7, Minor7, Major7, Major9, sus4, etc. and even slash chords

You can also hear what they sound like, even find it based on the Circle of Fifths.

>>> Chords Backward Search

Stumbled upon a new chord? Simply tap in the frets and the App will tell you what you're playing!

Customer Reviews

Double edit...

I just clicked "restore" and all the functionality the app had lost was returned to me. I have no idea why it loses your details after an update, but I am happy again.

Sorry for the 1-star review a while back.

Great app but small glitch with full version.

Great app I use it all the time but for some reason I have to keep on restoring my app from my purchase of the full version every time I open it to use all the tunings. Small complaint great app.

Great app if you like paying for premium multiple times

Got the premium membership for free a while back. Then it changed and I lost my premium, paid for it. Now it's gone again telling me I have to repurchase it (for the same account)...
