How It Works

Just pluck a string on your instrument – Tuna detects the sound using your device’s microphone. You’ll get instant visual feedback while tuning. No cables needed.

With our award-winning audio recognition technology, we guarantee you an insanely accurate tuning result. We use noise cancellation technology to eliminate background noises while you tune.
