Yeah, I’ve sketched a few screens. The trick is to keep the layout simple enough that you can swipe to a “fire” icon in the dark, but still show all the sub‑options—matches, flint, tinder. Minimalism saves cognitive load, but if you strip it too far you lose the context that tells you “this is the right tool for a cold night.” I usually use a single column, thick icons, and a tiny help overlay that you can pull up with a tap. It’s a tight balance—add a second column and you’re drowning in options, cut too many details and the app feels like a joke. The key is to test it in real conditions; a UI that looks clean on a phone screen is nothing if you can’t find the fire starter in a flash of darkness.
