Always know what to do next

Plans break. Priorities shift. Circadium re-sorts your day.

Free while in beta.

The real cost of a broken plan isn't the lost hour — it's the deciding that follows. A gap opens, three things could fill it, and you end up spending the free hour deciding what the free hour is for.

Circadium computes a week around your goals, commitments, locations, and constraints — and when life shifts, it re-sorts, so the next right thing is already waiting.

The result isn't a perfectly optimized calendar. It's a week you can actually live.

The whole idea in two minutes — a week built, a plan broken, and the re-sort that follows.

Planning is two jobs.

Deciding what matters — and re-deciding when it all happens, every time something moves.

The first job is yours alone. It takes judgment: your goals, your values, your call.

The second is logistics. Durations, deadlines, locations, travel, open slots — a constraint problem with a thousand moving pieces, and it reopens every time the day shifts.

You were never meant to solve that one by hand.

Circadium takes the second job off your hands entirely. You set the direction, and it builds the week.

The Circadium calendar: a generated week of goals, fixed plans, and travel blocks, with the engine console open beside it. — A generated week — deadlines, windows, the school run, and the travel between them, placed in one pass. The engine explains itself in the console on the right.

When the plan breaks, the deciding begins.

A meeting runs over. The gym is now impossible, and there are ninety orphaned minutes where the plan used to be.

The language, the instrument, the training, the side project — any of them would count. But choosing between them costs more energy than doing them, so too often the gap goes to nothing.

That deciding is the work Circadium takes over.

When something moves, the whole week is recomputed around what matters most right now. The gap arrives with its answer already in it.

And it's yours to overrule — drop anything in by hand, and the week flows around it.

No end-of-day re-planning session, no willpower spent on triage.

You decide what matters.

The engine decides what's next.

A productive day can still be a wasted day.

You can clear your inbox, finish a dozen tasks, sit through every meeting — and make no real progress on anything that matters.

Doing more isn't the same as moving forward.

Productivity is a means. Its point is what it buys — the language learned, the strength kept, the people you show up for.

That's why Circadium doesn't start with a task list. It starts with the roles you play in life — parent, friend, professional — and builds the week outward from them.

A schedule is a claim about what your life is for. Circadium's job is to make your weeks match it.

The Circadium mindmap: roles radiating from the center into categories, goals, and tasks. — Roles at the center; everything you're working on grows outward from them.

The part you never think about.

Your goals aren't independent. The campaign feeds the quarterly review; the training plan leads to the race. Order lives between them.

Circadium holds that web — queues, dependencies, sequences across goals — and every placement, every re-sort, respects it.

You see a calm week. This is what's holding it up.

The Circadium graph view: queues and dependency connectors between goals laid out on a time axis. — Queues and dependencies across goals, resolved on a time axis. You never have to look at this — it just has to be true.

What's in it

Four moving parts.

A scheduling engine

Tell Circadium what matters — type it in, or talk it through with the built-in assistant. It returns a week that respects your goals, your deadlines, and the constraints around them, without you arranging a single block.

Locations & travel

Every place you work from, every commute between them. The engine knows what's reachable and routes time across driving, transit, cycling, and walking.

Time-aware categories

Define when each part of life is allowed to happen. Strict windows that block everything else, soft ones that only suggest. Deep work mornings, errands after five.

Goals with subtasks

Break large goals into ordered steps — and let goals depend on each other. Buying a car waits on the license, the savings, the job that pays for it. The engine schedules the whole chain knowing it, woven around everything else in your week.

Also in the box

AI assistant

Set up goals, weeks, and categories in conversation. Runs on your own key, stored only on your device.

External calendars

Google, Outlook, or any calendar feed — the engine schedules around what's already booked.

Repeating items

Flexible repeats that find their own spot each period. Twenty minutes of French, every day, wherever it fits.

Habit tracking

A month grid over your repeating items: streaks, rates, and the days that count.

Capture inbox

Jot things down the moment they surface, triage later. Nothing untriaged clutters the calendar.

Split tasks

Big tasks placed as chunks — set minimum and maximum sizes, daily caps, and breathing room between them.

Queues

Ordered streams of work: each item scheduled after the one before it finishes.

Daily limits & allowed times

Cap a goal's minutes per day, or confine an item to the hours you allow.

Manual control

Drag anything anywhere — the rest of the week recomputes around your call.

Your data

Export everything you own as a single file, any time. Import it right back.

Go live your week.
