## Description

Tune your instrument with a clear, steady readout. Pitch detection runs on your phone — offline, no account, no ads.

Your audio never leaves your phone.

Tuner is a chromatic tuner that listens through your microphone and tells you the exact note you're playing — entirely on your device. No internet, no account, no tracking. Don't trust it? Turn on airplane mode: turn off Wi-Fi and cellular, and it keeps working. Nothing is ever recorded, and nothing is ever uploaded.

Play a string, press a key, or sing a note. A big, clear note name fills the center (like A4), with the live frequency in Hz and a smooth 180-degree needle that swings with every cent. The moment you land in tune, the whole note glows yellow — you tune by feel, not by squinting at numbers.

WHY OMITTUNER IS DIFFERENT
Most tuners pay their bills with ads, accounts, or tracking of mic-adjacent data — or gate real accuracy behind a monthly subscription. Tuner does neither. No ads. No subscriptions. No accounts.

PRIVATE BY DESIGN
• Microphone audio is analyzed in memory and discarded instantly — never written to disk, never uploaded.
• Pitch detection runs 100% on device with pure-DSP YIN math. No machine-learning model, no cloud, nothing sent to any server.
• Zero analytics, zero telemetry, zero third-party SDKs. Privacy label: Data Not Collected.

WHAT IT DOES
• Real-time pitch detection, fast enough to follow your tuning peg as you turn it.
• A huge, readable note name plus the live frequency in Hz — legible across a music stand.
• A 180-degree needle that leans flat or sharp, and glows when you're within 5 cents.
• Adjustable concert-pitch reference — 432, 438, 440, 442, or 444 Hz, one tap, remembered next time.
• The screen stays awake mid-session so you can keep both hands on the instrument.

GREAT FOR
Guitar, bass, ukulele, violin, cello and other strings; brass and woodwind intonation checks; singers and choirs warming up; piano reference checks; students and teachers in any room.

HONEST ABOUT WHAT IT IS
Tuner reads what your microphone hears using 12-tone equal temperament to within about 5 cents, across 25–4500 Hz. It's an excellent everyday and practice-room tuner — it isn't a studio strobe and doesn't claim that precision.

NO SUBSCRIPTIONS, NO ADS
No subscriptions, no in-app purchases, no ads. That's the whole deal.
