Zent — The app for working with yourself. The coach that makes you move, when no one else is making you. You already know what matters. You've planned it, listed it, told yourself you'd do it. Then the day happens, and most of it doesn't. That's not a list problem. That's the part where you're alone with yourself, trying to get yourself going. Zent is built for that part. You put your real life in — work, projects, routines, the things you keep putting off. Zent runs the day with you. When you open the app, you don't see a list. You see one concrete thing to do right now, and you can trust it, because Zent is holding the rest. How Zent works with you Tell Zent what's on your plate, in your own words — out loud or in chat. Zent structures it WITH you: tasks, routines, projects, the stuff you've been avoiding. Then it watches what gets done and what keeps slipping, and asks why. The night before, Zent meets you with a short preparation tuned to whatever is in the way — so tomorrow morning has nothing left to decide. When you open the app, one thing is already picked, with a small opening move to get you moving. While you work, Zent watches the time you said you'd give it, and if you drift past it, it pings: still on this? The outside-your-head check the wandering brain can't generate on its own. What Zent does that other apps don't Stuck and can't start. Zent names what's in the way and meets you with a small opening move — drawn from a wide body of research on how people actually start hard things, matched to your specific situation. Forgot what matters. Zent watches the areas of life that keep getting drowned by the urgent stuff, and pulls them back into the day before they slip further. Too many things, no idea where to begin. The decision is removed, not made faster. Zent picks one based on deadlines, importance, time, and what's been waiting. Goal too big and vague to act on. Describe it. Zent works it down with you into concrete things you can actually start tomorrow. Nothing to learn. No system to set up. Why people choose Zent Zent is for people who want to actually do what they say they will. Not better lists. Not another planner. The app that runs the day with you when no one else is — sees what keeps slipping, picks the one thing that needs to happen now, and stays with you while you do it. If you often know what you should do but can't make yourself do it, Zent gives you a more practical way to move from stuck to done.

The only productivity app you design yourself. Most to-do apps make you bend to their rules. To Do Machine flips the workshop on its head — open the back panel, swap the parts, paint it your color. Talk to it in plain English and watch your task inbox, your projects, and your entire workflow rebuild themselves in real time. Built natively for Mac and iOS. Perfectly in sync. — WHO IT'S FOR — For the people who've tried every to-do app and bounced off them all. For the ones who keep building systems in Notion, then abandoning them. For anyone whose brain works a specific way and is tired of apps that don't. To Do Machine isn't another opinionated workflow. It's a workshop where you build the one that fits you. — DESIGN IT YOURSELF — Tell To Do Machine what you want and it remakes the app around you. "Make the inbox darker and put due dates on the right" — done. Switch any project to list, kanban, calendar, focus, or blueprint view. Invent your own statuses, fields, and automations, project by project. Every tweak syncs to all your devices instantly. — AI THAT DOES THE TYPING — Just say what's on your mind. To Do Machine writes the tasks, breaks them into projects, sets reminders, and finds time on your calendar — no tapping the + button. "Plan my Q3" → full project with milestones, weekly check-ins, and time blocks. Auto-triage your inbox: priority, due dates, parent project. A daily standup that drafts your day before you've finished your coffee. — CALENDAR IN, DAY OUT — Connect Apple or Google Calendar and your tasks thread themselves between your meetings. Two-way sync with Apple or Google Calendar. Time-blocking that respects your meetings, focus blocks, and breaks. Move a meeting and your tasks move with it. — INSTANTLY SYNCED BETWEEN iOS AND MAC — Tasks, projects, and calendars sync in milliseconds. Custom layouts and themes travel with you. Redesign your inbox on Mac at lunch — it's waiting on your iPhone by the time you stand up. Assembled in Brooklyn, NY. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
