Frequently Asked Questions

Brusha is a drawing app built around a real-time particle physics simulation (Android and iOS). Instead of flat strokes, every stroke spawns hundreds of physics-driven "bubble" particles that flow, collide, and settle on the canvas.

Drag your finger across the canvas to paint — each stroke spawns a burst of particles that flow and settle. Use Undo/Redo in the top bar, the Eraser to remove particles, the Hand tool to push placed particles around, and Freeze to pause the physics and draw on top of a static scene.

Yes — pick from the color swatches (a handful of solid colors are free; the rest, including Rainbow, are Premium). In Settings you can also set the background to a solid color, a Rainbow background that slowly cycles through colors (Premium), or a photo imported from your device.

Tap Save (screenshot) in the top bar to save the canvas as an image, or the record button to capture a video (5 sec free, up to 60 sec Premium). Saves go to your gallery on Android (Pictures/Brusha) and Photos on iOS.

Free-tier screenshots and videos get a small Brusha watermark; Premium removes it. Live drawing on screen is never watermarked — only saved files.

Subscriptions are billed and managed by the store you subscribed through — Brusha has no separate cancel button:

• Android: Google Play → profile icon → Payments & subscriptions → Subscriptions → Brusha → Cancel.
• iOS: Settings → your name → Subscriptions → Brusha → Cancel Subscription.

Cancelling stops the next renewal — you keep Premium until the period you already paid for ends.

No, as long as you're signed into the same Google/Apple account you subscribed with. The app re-checks your entitlement with the store on every launch and restores Premium automatically — no "restore purchases" step needed.

Lower the "Max bubbles" slider in Settings, or reduce Mass/Size on the brush menu — large particle counts are the main cost on lower-end devices.

Make sure you're signed into the store account (Google/Apple ID) you purchased with, then relaunch the app — it re-verifies your entitlement on every launch.
