Description
Koi – Build momentum. One day at a time.
Koi is a self-care app designed to help you stay consistent without pressure. Build routines, track goals, and complete everyday activities like exercise, meditation, or reflections, all in one calm, flexible space. Koi focuses on progress, not perfection, so you can keep moving forward even when life gets busy.
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.
What you can do with Koi
• Create daily habits and set reminders
• Set personal goals with milestones and track progress
• Write reflections with photos and audio
• Create simple, structured and nested lists
• Track mood, water, food, exercise and more
• Build custom trackers for anything you want to measure
• Use focus timers and meditate with natural sounds
• Personalise your experience with beautiful themes
• View your progress over time
• Keep everything organised in one place
Your Koi Pond
Collect coins and feed your koi. 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.
