Improved tuning display clarity and stability. Keeps the screen awake while tuning. No subscriptions. No ads. No email. No personal data. Just a clean, analog-inspired tuner that gets it right — every time. A440 by Ownly delivers studio-grade accuracy (±1 cent) with a smooth, analog meter that feels alive. Whether you’re tuning guitar, bass, or other acoustic instruments, it locks on instantly — no lag, no noise, no distractions. - Within ±1 cent accuracy for most instruments. - Selectable reference pitch (420–460 Hz, including 432 Hz) - Adjustable mic gain for reliable detection across environments - Simple analog-style meter with haptic calibration feedback - Clear visibility in light or dark mode - No subscriptions. No data collection. No ads. No distractions. Buy once. Tune forever. Notes: - A440 by Ownly is optimized for guitar, bass, and other standard-range stringed instruments. It performs accurately across the full chromatic scale but may show brief movement during the initial attack of percussive instruments (like piano or drums)—this is normal and reflects how those instruments produce harmonics. - Designed for simplicity, precision, and reliability—not for multi-instrument or polyphonic analysis. - Minimal, anonymous usage analytics are collected to help improve performance and reliability. No personal or identifying data is ever stored or shared.
