FAQ

FAQ

Does it work on my phone?

Yes. Rub the screen with your finger and the particles follow; in Fireworks mode, they burst where you tap. The page won't scroll while you're touching the canvas, so swipe outside it to scroll down.

Will it slow down my computer or drain my battery?

It pauses automatically when you switch tabs or scroll the canvas out of view. If it still stutters, lower the particle amount. If Reduce Motion is on in your device settings, it starts with fewer particles and the auto demo off.

How do I turn off the auto demo?

Uncheck “Auto demo when idle” in the side panel. When it's on, a virtual finger starts drawing after about 2.6 seconds without input.

Are my settings saved?

Your mode, color theme, particle amount, trail length and auto demo choice are saved in this browser, so they're the same next time. There's no option to save the canvas as an image.
