• Voice calls have new voices. Every character now has a voice of their own that fits who they are. • Calls sound smoother: each reply is spoken in one steady voice from start to finish. • The new voices are a one-time download of about 220 MB the next time you call. The old voices are removed after it.

sounded like my character but roleplay was bad as i was expected to speak for everyone but the bot so there was a lot of standing around and doing nothing and waiting while I was expecting it to talk, but it was expecting me to talk

Response from developer

Thanks for the honest feedback, and sorry the scene stalled. Our characters tend to wait for you to move the story, which can feel slow if you want them to take the lead. We're noting this. If you want to share more, write to support@get-castmates.com and we'll look into it.

Best offline rpg app

Castmates is a dream for roleplaying fans! The offline AI runs entirely on device!The characters stay in role, remember past interactions, and make every session feel alive.
The developer’s responsiveness was impressive. When I had questions, they replied fast and it was clear they truly cared. That kind of dedication is rare and makes the app even better.
With 32 unique characters across 8 genres and the ability to create your own, Castmates offers endless creativity. Whether you love fantasy, sci-fi, romance, or mystery, there’s a ready-made scene (or 96!) to jump into.
For anyone who values privacy, creativity, and seamless storytelling, Castmates is a must-have. 10/10!
