Build beats in your space.

Turn any surface into a playful drum machine. Place reactors in AR, drop bouncing balls, and let physics create evolving rhythms. Every reactor carries its own sound—tap to pick one from 100+ effects, or shuffle for happy accidents. Add beat loops and tone sequences, tweak speed, bounciness, and gravity, and watch (and hear) your room groove.

How it works

– Move your device to scan—use the focus brackets to place your first reactor.

– Tap + to add more reactors and shape the rhythm in space.

– Tap a reactor to choose its sound from the built-in library (or randomize).

– Adjust Speed, Bounciness, and Gravity to sculpt the feel.

– Blend in beat loops and tone sequences at 125 or 130 BPM.

Highlights

– 100+ sound effects for reactors, plus curated loops & tone lines

– Real physics = natural grooves (balls live ~10s for constant motion)

– Tap-to-assign sounds with searchable picker & instant preview

– Quick BPM switch (125 / 130) and global speed control

– Glass UI (iOS 26) — cleaner, brighter, more touch-friendly

– Pause/Resume, randomize sets, long-press to delete reactors

– Works offline. No logins. No ads.

What’s New

– Complete UI redesign with the new iOS 26 Glass style

– New coaching overlay & focus square for faster placement

– Rebuilt audio engine & sound browser (search, preview, tap-to-apply)

– Record an audio session and share by mail or Air-Drop

– Snappier performance, smoother animations

– Pan on empty space to move the directional light (orbit + height) for dynamic shadows

– General polish across AR placement, labels, shadows, and controls

Tip: Spread reactors at different heights and tweak gravity for polyrhythms. Short bounces = tighter grooves; higher throws = airy, evolving patterns.
