What type of apps are you looking for?

Interactive - there's the Steam game Karryyn's Prison (only played a bit of the demo and it seems ok) and VRPlayspace (which is free, but most "experiences" are DLC: and only just worth it IMHO).

Using third party such as Xtoys.app for games such as VirtualSuccubus (which I've just stream a bit of on Chatubate) and the via the buttplug.io suite there's various vibe sequencers, Video Sync Script players and then games such as Besti, FarmD, Lustbound, and add ons for games such as Ultrakill, many Japanese games, Skyrim, CS:GO, League of Legends and many more.

Finding people: at the moment, there's Lovesenselife.com and the Tophy app - along with Reddit where you can try to find people: but be careful of scammers asking for money.

It does. You can connect it to your fans toy and then they feel your thrusts and vice versa. Make a menu item for your fan to control and give you pleasure. It keeps the show exciting and gives the fanbase something new to get their hands around you. Happy camming!
