Notes:
* A440 by Ownly is optimized for guitar, bass, and other standard-range stringed instruments.
* The tuner performs accurately across the full chromatic scale but may show brief movement during the initial attack of highly percussive instruments such as piano or drums. This behavior is normal and reflects the harmonic complexity of those instruments.
* Designed for simplicity, precision, and reliability rather than multi-instrument or polyphonic analysis.
* Minimal anonymous usage analytics may be collected to help improve reliability and performance. No personal or identifying information is ever stored or shared.
• New premium Space Gray and Classic Aluminum finishes
• Refined hardware-inspired visuals and analog meter realism
• Improved interface polish, consistency, and usability
• Stability improvements and tuning workflow refinements
