Several kinds of surface available :
- Heat : Regular heat-sensitive surface
- Flame : Fire at your fingertips
- Fantasy : Let the moving patterns hypnotize you...
- Sky : Relaxing clouds at your fingertips
- Metal : Shiny chrome reflections
- Spirit : Bending the Laws of Physics, really hypnotic...
- Rainbow: Psychedelic colors
- Glow: Radioactive glowing surface
- Islands: Create your own archipelago!

... and much more! Some of them available as in-app purchase.

For best results move your fingers very slowly as the touchscreen needs time to heat!

- Save your creations to your camera roll

Straightforward, fun, and useful

HeatPad does exactly as advertised - no more and no less. Good if you need to waste a few minutes or wind down from a panic attack. Watching the colors fade can provide a soothing visual to tire your eyes out, so you can go to sleep easier.

It's also really helpful if you're having screen sensitivity issues on your device, bc the colors change wherever it senses touch (obviously). Just press/drag on slow-fade mode, watch the colors change (thus illustrating the screen sensitivity issue), then take a screenshot for reference in case of repair.

All in all, a handy little app.

Symmetry 😍

Overall a great app. I love how you can unlock all of the pretty colors without spending anything. The only thing I think that can be improved is put symmetry as an option when you're not connecting with someone else. Very beautiful and relaxing!! Also, I think that a new update should be soon, fixing a few small bugs and maybe adding this to the Apple Watch as well. I absolutely love this app. It’s very satisfying and fun. Please consider making this compatible with the Apple Watch!!

Why are y’all so stupid 😂😂😂😂

Some of you think this is actually a HEATING PAD that warms your hand. How old are you, 5? You really believe your device will warm your hand? Overall, this game is pretty good, but why must we stay on the game for so long just to achieve all the modes? Why not watch ads or something. Although, I get that this is a drawing game, but I wish there were challenging levels etc.
