Why Kiu
Habits stick better when they stack
Most habit apps give you a flat checklist — and flat checklists get abandoned. Kiu is built on habit stacking: attaching new habits to the moments and routines you already have.
Group your habits into stacks by context — Morning, Work, Evening, Night or anything you invent — and complete them as one flow. One habit triggers the next, and your routine carries you forward.
Features
Everything you need to stay consistent
Simple on the surface, powerful underneath — and no guilt, ever.
Flexible habits

Streaks
Watch your streaks grow and stay motivated — don’t break the chain.
