I haven’t heard on any software that connects the two together so that they are synched.
Lovense has its own remote control software Live Control though, but I assume you already know that.

Lovense is also mentioned in the following thread, but I doubt it’s what you are looking for:

That thread is how to use one one toy, not two in sync, but it shows options on how to connect to Lovense without Lovense Live-Control.
