[Gear VR] Any analytics tools available for UE4 to grab metrics from Gear VR users ?

Basically looking into something to track number of downloads, number of times each users runs the app/game, number of unique users per region, number of uninstalls, average length of usage session, gender breakdown, etc. 

Something like Steam statistics or Google Analytics, but leaning into VR.

Is there anything like that already available to Gear VR devs using UE4 ?

Thanks
