Been working on this for a while now, figured I'd share here since I just pushed a big update.

What it is?

It's a virtual companion app. You've got Aiko, she lives on your phone, and you build a relationship with her over time. Not like a visual novel where you pick dialogue options and get a preset story. You actually talk to her, she responds, and the relationship develops based on how you interact.
She starts out as a stranger and you work your way up through acquaintance, friend, close friend, and eventually romantic. Takes time though, this isn't something you rush through in an afternoon. The whole point is she feels like someone you're actually getting to know.

What makes it different?

She remembers things. Like actually remembers. Tell her your job, your hobbies, stuff about your life, and she brings it up later. There's a facts manager where you can see everything she knows about you, fix anything she got wrong, or add stuff manually.
She has her own personality that you can customize. Adjust how playful she is, how shy, how affectionate, that kind of thing. So she feels like your companion, not just a generic anime girl.

She also has needs and routines. Gets hungry, gets tired, wants attention. You'll see her eating meals, sleeping, doing activities throughout the day. Ignore her too long and her mood reflects it. Makes her feel like she's actually living her life rather than just waiting for you to open the app.
