Your calendar, but it actually plans your work.

TimeFlow is a calendar that plans your day for you. You add the work you need to do — how long it takes, when it's due — and TimeFlow slots it into the gaps between your meetings during your working hours. Group related work into projects with deadlines when you want more structure.

A normal calendar holds appointments. TimeFlow plans your actual work too — it puts your tasks and habits into your free time, respects your working hours, and rearranges when your meetings change. Don't like where something landed? Drag it and it stays put.

Projects are goals with a deadline — "Q3 Launch," "Move apartment," anything finite. Add tasks and habits to a project and TimeFlow makes sure they fit before the deadline (or warns you when they won't). You can break a project into phases like Discovery, Build, Launch — or pick from a template — and you get a kanban board for that project. Projects can also have their own working-hours schedule, separate from your default.

MAX is a second-tier scheduler that uses an LLM to plan your week with judgment — not just by greedy slot-filling. You click the wand button in the toolbar, watch the model think live, and approve, refine, or discard the proposal. The regular auto-scheduler then reflows around the anchors MAX places. You get 30 MAX runs per month and you can refine each plan up to 5 times for free. Pick OpenAI's GPT-5.5 (default) or Claude with extended thinking; switch in Settings → MAX.

The assistant lives in a drawer (⌘I) and can read your tasks, events, projects, habits, and recent activity, then propose changes you approve before they apply. It creates and updates anything on your calendar — tasks, events, projects, phases, habits, calendars, schedules — and can trigger the auto-scheduler. You can drop in images and PDFs and it'll read them. The free tier includes 25 messages per account.

Yes — TimeFlow ships a Model Context Protocol (MCP) server so you can connect Claude Code, Cursor, Claude Desktop, Windsurf, or any MCP-aware AI client. Your AI signs in with your TimeFlow account via OAuth 2.1 (no API keys, no passwords) and can list, create, update, complete, and delete tasks, plus list projects and phases. Calendar events and schedules are intentionally out of scope for MCP today — those stay under direct user control. See /integrations/mcp for the one-line install commands.

When you use the chat assistant or AutoScheduler MAX, TimeFlow sends a snapshot of your active workspace — task and event names, durations, deadlines, working hours, recent activity — to the model provider you've selected (OpenAI or Anthropic). You can flip a privacy switch in Settings → MAX to redact task titles before they're sent: durations, deadlines, and ids still go, just no human-readable names. We don't share your data with anyone else, and the providers don't train on it under their API terms.

Right now beta access is free — billing rolls out in the coming weeks. When we turn it on, the price is $5/month for beta subscribers, and that price stays locked for life as long as you stay subscribed. After we exit beta the price goes up to $10/month (or $96/year) for new signups — but anyone who joined during beta keeps the $5 rate forever.

Yes. Two-way sync — meetings you create in either place show up everywhere. It stays fast even with thousands of events.

Press play on any task to start a live timer. Stop it and your time logs to the task automatically. Works across devices — start it on your laptop, see it running on your phone. Survives a browser refresh.

Daily, weekly, monthly, or any custom rhythm. Set a target like "5 hours of exercise per week" and TimeFlow places the time for you. If you miss a week you can choose to start fresh or carry the missed hours forward.

Yes. Light mode, dark mode, or follow whatever your system is set to. Pick from eight accent colors — purple, blue, indigo, teal, emerald, amber, rose, slate — to recolor the whole app. Group and event colors are separate.

Open TimeFlow on your phone's browser, tap "Add to Home Screen," and it runs full-screen like a real app. iOS and Android both supported, no app store needed.

TimeFlow is built for personal planning rather than team scheduling. It's keyboard-friendly, fast, and free during beta. Anyone who wants their calendar to plan their work — not just hold their meetings — should feel at home.

Nothing bad happens. TimeFlow notices the time has passed and slots the remaining work into your next free slot. The time you actually did work is logged through the timer (or you can log it manually).

Your data is yours alone — only you can see your own tasks, events, and habits. We back up daily. The app is in beta, so we'd suggest not making it your only system of record yet, but the security setup is the same we'd use for a finished product.
