Hey Product Hunt! 👋 I'm Zhanibek, the solo maker behind Cert. I built Cert because I kept running into the same problem with every habit tracker I tried. At first, checking off habits feels great. But after a while, it's way too easy to tap "Done" even when you didn't actually do it. Once I realized I could lie to the app whenever I wanted, my streak stopped feeling real... and eventually I stopped caring. So I built Cert around one simple idea: a streak should have to be earned. Every day, you prove you completed your habit with a photo, a short video recorded in the app, or a GPS check-in. An AI reviews the evidence before your streak counts. If you miss a day, your streak resets. It sounds harsh, but that's exactly why a 30-day streak in Cert actually means something. A few things I really like about it: * The AI isn't trying to judge how good your photo looks. It's looking for honest proof. It'll accept a blurry gym selfie if it's real, and reject something that doesn't actually show you completed the habit. * You can do challenges with friends. Everyone builds a shared streak, and whoever finishes last has to spin a wheel of dares that the group created. * The free version isn't just a trial. You get one goal with unlimited photo verification. Pro adds video verification, GPS check-ins, unlimited goals, and detailed stats. This is a solo project (with a lot of AI helping me build it), and I'd genuinely love honest feedback. If you've ever downloaded a habit app, used it for a week, and quietly stopped opening it, I'd especially love to hear what you think. Give it a try, try cheating if you want 😄, and let me know what feels good, what feels frustrating, and what's missing. Every piece of feedback helps make Cert better. 🙏
