Onyx: Pitch Pipe app analytics for December 31

Start off on the right note every time with Onyx. This beautiful pitch pipe sports a three-octave range in C-C or F-F, with your choice of carefully crafted sounds: choose piano or clarinet to hear your note for several seconds, or switch to continuous playback mode* to loop strings or horns for as long as you like. Or, for pinpoint accuracy, use our custom sine wave generator instead and avoid those annoying loud pops that other apps can create. On iOS, all sounds can be tuned to your preferred frequency (due to technical limitations fine tuning is only available when using the Tone sound option on Apple Watch). Use the interactive widget and the watch app for instant access from just about anywhere. Onyx even works when your device is in silent mode, so you don't have to worry about embarrassing interruptions. That's our pitch, now find yours! * Continuous playback mode is currently only supported within the app and cannot be used with the Today View widget or on Apple Watch.
