Hey Product Hunt! 👋 I'm the solo developer behind Just One — and I want to be upfront about something before you read any further: This app is not for everyone. If you need to see your full task list, manage projects, or plan your entire week in advance — Just One will frustrate you. And that's completely fine. But if you're the kind of person who opens their to-do app every morning, feels immediately overwhelmed, and closes it without doing anything — this might be exactly what you've been looking for. --- Here's the one rule Just One is built around: You can only work on one task at a time. You cannot create a new task until the current one is marked done. That's it. That's the whole app. No lists. No backlogs. No priority toggles. No project folders. No complexity. Just the thing that matters right now — sitting on your screen, waiting for you to finish it. --- What happens if you don't finish by end of day? The next morning, the app asks you one honest question: carry it forward, or let it go? You have to decide. You cannot quietly abandon something. That gentle accountability is very much the point. --- Why I built it: I often have a huge list of items on my to-do list. And because of the long list, I often feel demotivated. Not because I was lazy — but because the list itself was the problem. Every morning it reminded me of everything I hadn't done. So I deleted everything and gave myself one rule: finish before you start the next one. My output stayed the same. My anxiety about work completely changed. I built Just One because I wanted that rule to live somewhere. --- A quick note on privacy: Just One collects absolutely nothing. No analytics, no tracking, no account, no server. Your data lives on your device. Always. I'd love to hear what you think — especially from people who have tried every productivity app and found them all too complicated. This one was built for you. Ask me anything in the comments. 🙏
