About this app
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!…

Evidence and review signals
This is where the page changes from an app-store listing into an evidence report: findings, important reviews, pricing and a dated history.
What we measured

Five-star share of ratings
Under 65% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence about the app, not a finding about it.
