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!
