The idea behind HealUp is that the most valuable thing a productivity tool can do is hide information from you. When you see one clear action on screen, you do it. When you see thirty, you spend energy deciding which one, and often pick nothing.
How it works: you type a task, AI breaks it into concrete steps (not vague advice, actual next actions like "open Google Docs and create a blank document"), and Execute Mode shows you one step at a time. Full screen, nothing else visible. Finish it, next one appears.
This is the first thing I built that I actually use myself every day. Looking back, that's probably why the others failed. I was building for imaginary users, not for myself. This one made $680 in its first two weeks, which after 4 years of $0 and 6 failed startups felt like a lot.
No signup required. Guest mode is fully functional. You can try it right now without creating an account.
Looking for feedback on whether others have found that reducing visible information helps them focus, or if it creates anxiety about what you're not seeing. I've heard both and I'm still figuring out the right balance.
