Kotsu Kotsu is a quiet place to keep meditating. "Kotsu kotsu" is the Japanese sound of stone meeting stone — and a word for steady, unhurried persistence.
No noise, no clutter — just a stone, your breath, and a few unhurried minutes. Tap to begin, and watch a single stone rise gently through the still water.
WHAT YOU CAN DO
• Sit for as long as you like — pick any length and begin with one tap.
• Breath sensing (optional): your phone gently reads the rhythm of your breathing to guide a calmer pace. Audio is analysed on your device in real time — never recorded, stored, or sent anywhere.
• Build a streak: come back each day and watch your cairn grow, stone by stone.
• Guided lessons: learn real techniques — breath focus, body scan, loving-kindness, walking meditation and more — explained step by step, as if a teacher were sitting beside you.
• A living map: see fellow meditators around the world sitting at the same time (locations are always blurred for privacy).
• Stats you'll actually look at: streaks, total time, calm trends, and a global streak ranking.
PREMIUM (optional)
Every core feature is free. Premium unlocks the full library of in-depth guided lessons, with new teachers and styles added regularly. You can also earn premium lessons for free by keeping a daily streak.
PRIVACY FIRST
Microphone audio for breath sensing is processed entirely on your device and never leaves it. Map locations are always coarsened so no one can be pinpointed.
Sit. Breathe. Stone by stone.
Keep meditating. Stack stones, breathe, find meditators nearby, grow a streak.
