Why Koi?
In Japanese culture, the koi fish (鯉) represents perseverance, strength, and transformation, swimming upstream against strong currents, one day at a time.
“Koi” (恋) also means love. Building habits is an act of self-care. Small, repeated actions are how real change happens.
Koi is designed around that idea.

Your Koi Pond
Your koi are your self care pets. Collect coins and feed them, and watch them grow from fry to elder as you build consistency. Each one a living reflection of your progress. Name them, care for them, and raise your collection one day at a time.

Designed to feel natural
Koi is built to be lightweight, distraction-free, and easy to return to, even after time away. Whether you’re starting a new routine or rebuilding one, Koi meets you where you are.

Who Koi is for
• Anyone building habits without pressure
• People who struggle with strict streaks
• Users who want simple structure, not complexity
• Those who prefer a calm, simple design

Build momentum. One day at a time.
