Kuu: Ride Out the Urge

Caught yourself scrolling again at midnight?

Kuu (空, "emptiness") is a refuge app — a place to escape TO the moment an urge to scroll or binge hits. No blocking, no surveillance. Just a calm place to spend the few minutes until the wave recedes.

■ Wave — breathing starts the moment you open the app

• One simple pattern: 4-7-8 (inhale 4, hold 7, exhale 8)
• Hear exactly when to inhale, hold, and exhale — three guide sounds (temple bells, singing bowl, ocean waves)
• The chemical wave of an urge peaks in about 90 seconds — visualized with a timer
• Surfed it or got swept away: log it either way, without blame

■ Gate — put 90 seconds in front of the app you reach for

• Stand it in front of Safari, X, Instagram, YouTube, Kindle, or any app you choose
• Set up with a single action in a Shortcuts automation
• After 90 seconds, you decide: open it, or turn back
• Nothing is forcibly blocked. It only adds a pause.

■ Wisdom — 24 cards from East and West

• Buddhist emptiness, Yogacara, Zen, and Stoic philosophy
• The science of dopamine: wanting vs. liking, the pleasure-pain balance, the 90-second rule
• Practical tools: the 10-minute rule, HALT, cold water, urge surfing
• Every card ends with one small action to try right now

■ Stillness — slowly drifting ink-wash landscapes

• Moon and sea, mountain mist, a rock garden, bamboo, snow, stars

■ Log — statistics without shame

• Day streaks, waves surfed, a two-week chart
• Everything stays on your device. No account, no network, no ads.

An urge is a wave. It rises, peaks, and always recedes. Keep a place for those few minutes in your pocket.
