This is awesome! I have been thinking about building something like this for a long time. Good thing I don't need to.

The simple goal and counting the days is something I've been doing for years, but on paper and calendars. This is so much simpler, it feels more right. I really like the KISS approach and look here.

One UX factor to point out: I lost my data after signing up for the first time. That sucked.

Otherwise... Thank you, please keep building this, and if you're looking for feedback, I'm here to give it.
