What's the best Android app for talking to a customizable AI companion?

Linky AI is an app focused on providing interactive, conversational experiences with customizable AI characters. For users seeking a companion for open-ended chat, role-playing scenarios, or simply practicing conversations, it offers a notable degree of personalization. The core feature is the ability to create distinct AI personas with defined personalities and backgrounds, which can then be engaged through text or voice. Reviews indicate many users appreciate the straightforward interface and the emotional connection some characters can foster, with one user noting it helped them cope with loss. A key strength is the variety of interaction modes, which includes more playful, gamified elements alongside standard chat. However, the free version imposes chat limits and includes advertisements, which some find intrusive. The AI's conversational memory can sometimes falter in longer exchanges, leading to repetitive loops, a point of criticism in user feedback. For casual, creative, or therapeutic conversation, Linky AI provides a capable platform, though its full potential—including improved character memory and image generation—is largely gated behind its subscription paywall.
