Tun3r: Instrument Tuner

A tuner. Free, no ads, nothing to pay for. Play a note. The orb drifts amber when you're off, settles sage when you're in. Haptic response. Chromatic for anything. Instrument modes for guitar, bass, banjo, mandolin, violin, viola, cello, double bass, and ukulele — including alternate tunings like Drop D and DADGAD. Reads down to a low B. A440, 442, 432, 415 — one tap. The screen stays on while you tune. Nothing is recorded. No data, ever. Just a nice tuner.
