Show HN: NoZeroDay – strictly-enforced daily streak challenges

I got fed up with habit apps that let you "make up" for missed days or give you endless second chances. What's the point of a streak if you can just fudge it when life gets messy? So I built NoZeroDay around one brutal rule: miss a single day, and your challenge dies. No exceptions, no mercy streaks, no "oops I forgot" buttons.

Here's how it actually works: You pick a challenge length (7, 14, 30, or 66 days) and commit to showing up every single day with proof — could be a quick text update, a photo, even a voice note about what you did. The format doesn't matter, but the consistency does. Miss one day? Game over. Hit every single day? You actually earned that streak.

Why I made it this way: I was tired of apps that felt like participation trophies. The whole point is that it should be hard to maintain a real streak. When there's no way to cheat the system, you stop trying to cheat yourself. The psychology is pretty simple when failure is immediate and final, you find a way to show up. Even if it's just 5 minutes before midnight logging "did 10 pushups in my pajamas."

Want to try it? Jump in and start a challenge right now no signup fees or trial periods. I'm really curious to hear what you think. Does the zero-tolerance thing actually motivate you, or does it just stress you out? And how's the overall experience feel? Honestly, I built this for people like me who need that extra kick in the pants, but I'm wondering if I'm the only weirdo who finds the harshness motivating.
