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. Every sound option can be finely tuned to your exact frequency, and you can choose from four themes to find the look that suits you best. For instant access right from your desktop or Today View, use the interactive widget: just tap a note to hear it. That's our pitch, now find yours!
