HapticTerrarium

Haptic Terrarium turns your iPhone into a therapeutic instrument. It's a physics-driven micro-world where flowing sand, rippling water, smooth stones, and soft clay respond to your touch, your tilt, and your breath — all synchronized with real haptic feedback you can feel. Unlike passive meditation apps, Haptic Terrarium gives you something to do with your hands. Every interaction produces a distinct tactile sensation through the Taptic Engine: granular taps for sand, smooth waves for water, firm thuds for stones, and soft resistance for clay. TOUCH — Sculpt, scatter, and push thousands of particles with your fingers. Each material behaves differently under your fingertips. TILT — The accelerometer maps your phone's orientation to gravity. Tilt to cascade sand, slosh water, tumble stones, and shift clay. FEEL — Four unique haptic signatures make each material feel real. The Taptic Engine responds to every interaction, every collision, every tilt. BREATHE — A guided breathing mode paces your breath at the scientifically optimal rate of 6 breaths per minute. Particles gently gather and disperse in rhythm. Haptic feedback follows your breath cycle. DISCONNECT — Place your phone face-down to enter haptic-only mode. The screen turns off while calming vibration patterns continue, guiding your breathing through touch alone. No subscriptions. No ads. No data collection. No internet required. Everything runs entirely on your device. Built for adults who want a sophisticated digital alternative to kinetic sand, worry stones, and zen gardens.
