CheckMark
The gamified, no-install to-do list (Invite Only).
What it does
CheckMark was designed selfishly for personal use. There's nothing to install but it acts like an ap on your phone. It has a gold system, badges, awards and milestones to keep you engaged. You can color code, swipe left to delete, swipe right to send to the future and even share with a friend for support and validation. Advanced things like long term goals, regenerating tasks, the project library and the buddy system can all be grown into as you progress, so you won't feel overwhelmed.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
