Thank you, I'm glad you like Freya! Working on the next update atm featuring Sethi. She's getting a big overhaul to improve her story, so stay tuned~
As for running on desktop, the Formamorph windows/linux/mac app can run models natively, so you don't even need a second application running in the background for it. And on mobile, if you have LM Studio, you can actually enable the Serve on Local Network setting to allow you to connect to your PC and play on mobile too! All local, any time you want, offline. Def let me know if you have trouble setting it up by reaching out on the Discord.
