Viola tuner
A free viola tuner in your phone's browser: C G D A one string at a time, with a needle and the cents; A at 440 or 442 Hz. Nothing uploaded.

The microphone stays open while you tune and closes when you stop, when everything is in tune, or after half a minute of quiet. Nothing is recorded or sent.
How to tune
A viola is tuned C G D A, a fifth below a violin: its top three strings are the violin's bottom three. Start with the A, then D, G and C. Bow a long, even note near the fingerboard; the low C is easier to read bowed than plucked.
Use the fine tuners for the last few cents. If your section tunes to 442 Hz, switch the reference and every string follows.
The needle shows how far you are from the note the tuner expects, in cents: a hundred cents is a semitone, five or closer gets the tick, and anything inside twenty most people don't hear.
Then play something
The notes you tuned go into Brumm as a short melody, inside a club track with a beat and a bass. No account, no upload: the notes travel inside the link itself. Hum or play a line there, and it becomes an instrument.
The microphone is read in the browser and nothing is kept. How the site counts visits.
