A tuner should do its job, and then get out of the way.

Dial was designed to be clear and simple — with no annoying logins, subscriptions, or unnecessary flash.

It hears the string

Automatic detection across the whole range. You play, it names the note and shows how far off you are.

Standard tuning is free for all instruments. A one-time purchase unlocks the full set of extras — browse the charts.

Manual selection: G held, reading nine cents flat

Or tap the note yourself

For noisy rooms and stubborn strings, pick the target by hand and tune against it.

Designed by musicians.

We built Dial because we were tired of tuners that try to capture your attention and distract you. A tuner shouldn't feel like a social media app – it should feel like a nicely designed, minimalist gadget.

Get in tune.

Standard tuning is free, for as long as you like. Alternate tunings are a single purchase.
