Search Volume Data for iTunes App Store?

[TheSEOWiz]

Ok, so maybe I'm looking in all the wrong places, But where can I get good search volume data for searches done in iTunes app store? Or is this something that Apple just doesn't share?

Neither Apple nor Google straight-out give you keyword data in their consoles. However, there are a few workarounds.

Apple has recently added "Apple Analytics" that give useful data, including device types and referring sites. They likely may add KW data in future.

GP (Google Play) does not report keyword data in the Developers Console but (surprise!) when connected to one's GSC (formerly known as WMT), all sorts of juicy data (including keywords) is viewable in GSC.

App Annie is very useful for competitive research. It's the best tool out there, followed from a distance by Sensor Tower, App Figures and others. But the best guestimate for volume they offer is "Results" for an app store search, which just means how many apps show up for it. Sensor Tower has a guestimate volume based on the AdWords KW tool.

I have come across a cool site called https://www.appannie.com/ that gives you some analytics, but nothing like search volumes, or even better, ability to track rankings within Google Play Store or iTunes app store. Still new, but really hoping somebody does something like this.
