If you have phones or anything with an IMU that connects via Bluetooth or wifi, slimevr is easy to get into and works decently well. A good dedicated tracker would be good for about 30 minutes without resetting (which is a push of a button with bindings), but phones + other crap would need to be reset every few minutes or so.

I've used 5 phones this entire time, if you like to cuddle it's perfect, as you can slip under a blanket and still be tracked.
