Habitopolis turns your habits into a living 3D city. Every activity is a tower, every day is a floor — and the more you do, the hotter that floor's color glows. Hit a milestone and the floor instantly turns green. Drag towers to rearrange your skyline, share projects with friends (read-only, so only you can build), and post your progress with one click to X, Reddit, or LinkedIn. Not another checklist — your skyline, growing one hour at a time.
