Snacks Tuner

Snacks Tuner is a free tuner that opens straight to the needle. No ads, no account, no subscription, and nothing tracked.

Play a note and it shows what it hears, how many cents off you are, and whether to go up or down. A strobe strip catches the smallest drift, and each string turns green when it lands.

What's in it • Guitar, bass, ukulele, banjo and mandolin, plus violin, viola, cello and double bass • Resonator guitar, cavaquinho, mandola, octave mandolin, bouzouki and balalaika • Trumpet, clarinet, alto and tenor sax and French horn show the written note, the one you read. Trombone and flute show concert pitch. • A chromatic mode for anything else • Search every instrument and tuning, with the ones you've used lately on top • Alternate tunings: drop D, half and whole step down, drop C, DADGAD, open G, D and E, baritone, 7 and 8 string guitar, 5 and 6 string bass, double C and sawmill banjo, and fiddle cross tunings • Artist tunings, found by player or band: the setups 19 well-known guitarists actually use, plus C standard, open C and drop B • Sweetened tunings, including James Taylor's published offsets and "sweet thirds" • Reference pitch from 415 to 466 Hz, with sharps or flats • Tap a string to lock it, so a low string can't jump an octave • Reference tones, so you can hear the note you're aiming for • A little buzz when a string lands • Flip the display for a phone on a music stand. The screen stays awake while you tune.

Intonate Intonate checks your guitar's setup. Play the open string, then the same string at the 12th fret. It tells you how far sharp or flat the 12th is, which way to move the saddle, and how far, in mm and the nearest 64th of an inch.

Private by design The microphone is only on while the tuner is running. The sound is analysed on your phone and never recorded or sent anywhere. There are no accounts, ads, analytics or crash reports, and the app doesn't talk to a server at all. It works offline.

Why it's free Snacks is a design studio. Snacks Labs is where our designers build real software and put it out in the open. Most free tuners are a sales funnel, with chromatic mode behind a subscription and an ad between strings. A tuner is a basic tool, so we built a good one and gave it away.
