Onyx: Pitch Pipe 4.1

Experience the perfect start every time with Onyx. This exceptional pitch pipe offers a wide three-octave range in C-C or F-F, accompanied by meticulously crafted sounds. You have the option to select either piano or clarinet tones, allowing you to hear your desired note for a prolonged period. Furthermore, if you prefer seamless and uninterrupted playback, switch to continuous mode* and enjoy the looped strings or horns indefinitely.

Onyx goes above and beyond in terms of accuracy. By utilizing our custom sine wave generator, you can achieve pinpoint precision and avoid any bothersome loud pops that often plague other similar apps. Additionally, on iOS devices, all of the sounds can be finely tuned to your preferred frequency. (Please note that fine tuning is only available when using the Tone sound option on Apple Watch due to technical limitations.)

Convenience is at the heart of Onyx's design. With its interactive widget and watch app, instant access is always within reach, no matter where you are. What's more, Onyx seamlessly operates even when your device is in silent mode, eliminating the worry of inconvenient interruptions. That's our promise: Onyx helps you find your perfect pitch!
