About this app

A-Tuner Lite is a free chromatic tuner for a wide range of instruments, from strings to winds.

Play a note and your device's microphone picks it up. A rotating indicator and bar show whether the pitch is sharp or flat, while the note name, octave, frequency, and pitch deviation appear at a glance. Pitch deviation is displayed in 0.1-cent increments, helping you make fine adjustments with confidence.

The built-in tone generator plays an A4 reference tone, making it useful for ear-training practice as well. You can also adjust the concert pitch, input sensitivity, in-tune tolerance, and display theme to suit your instrument and playing environment.

Key features:
• Pitch deviation displayed in 0.1-cent increments
• Clear visual guidance with a rotating indicator and bar
• Note name, octave, and frequency display
• Adjustable concert pitch
• Automatic or manual input sensitivity
• A4 reference tone
• Light and dark display themes

Ratings and reviews

Greatest tuning app. no adds, no forced upgrades. should have a much much higher rating! I've tried others and ads or noisy backgrounds mess them up, but not this one.

Top achievement. Unlike many others it is sensitive only to the fundamental tone and intelligent enough to cut thru the overtones. End result is really correct and useable. Great for plugged string instruments.

Great, accurate tuner. Possibly the best on Play Store, and I have used and tried many. Will be using and testing over the next few weeks. My advice to the developer - don't fix what isn't broken. I'll be back to update. Thanks!
