Same as Annie_Blythe! (FIXED)

I have an iPhone XS Max just like them. As soon as I touch the screen, a bunch of random lines flicker and glitch around the screen. Can’t be cleared no matter what. Seems to be unfixable on the user-end of the app. Please fix this issue! It was quite a calming app, I have to say, but now I can’t use it properly due to it glitching out on iPhone XS Max! Will update review once this issue is fixed. Thank you in advance.

Edit: Thank you for fixing the issue!! 🖤

i cannot express how much i love this app. you can set the inertia level so your drawing fades quickly or more slowly and there are a ton of color schemes. it’s INCREDIBLY relaxing and has been a huge help in managing my bipolar disorder. they just updated for the new batch of iPhones and i’m so happy they’re back 😭

i can’t leave w/o saying you’re an idiot if you think an app is going to heat up your phone to the extent that you can use it to warm your hands. that’s ridiculous and your phone would get damaged if it got that hot. please don’t punish this app for being unable to meet your misguided expectations

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.
