Each one, briefly
KhioThat's us
An AI accountability friend you text on iMessage. Khio texts you first with morning and evening check-ins, follows up when you go quiet, and logs your workouts, meals (from a photo too), habits, sleep, cycle and budget from plain texts. It remembers what you tell it, works in group chats, and never pays for anything or sends an email without your yes. Tracking and unlimited reminders are on Pro.
