Your city
Every project is an apartment building and every task a home. Finish a task and someone moves in. Watch your city grow, reach milestones and share a picture.
Congratulations, you're the mayor of a brand-new city. It starts out quiet and dark, and the only way anyone moves in is when you get something done. Every task you finish lights up a window, and it stays lit for good.

How your city works
| In your city | In TodoCity | What you see |
|---|---|---|
| An apartment building | A project | It goes up when you start the project. The older the project, the closer to downtown it stands |
| A floor | A section of a project | You name it, like “1st Floor: Travel” or “2nd Floor: Program”. Tasks that aren't in a section live on the ground floor |
| A home | A task | A new task is an empty home with a dark window. Finish it and someone moves in, so the lights come on and stay on |
| A faint glow | Sub-tasks under way | Tick off some sub-tasks and the window starts to glow behind the curtains |
| Blinking amber | An overdue task | Someone's waiting at the door |
| A house | A task in no project | Little houses line the edge of town, and their porch lights come on once they're done |
| “Coming soon” plots | Someday ideas | Ideas you haven't planned yet |
| The “Moving in today” billboard | Today's timed tasks | Up on the building's roof, in time order |
| A rooftop light | A finished project | Every home in the building has someone living in it |
| A crane and trucks | A project just starting | A crane stands over an empty lot, and trucks circle buildings nobody has moved into yet |
| Luxury cars | Your tallest tower | The project you've finished the most of |
| Population | Every task you've finished | Your number as mayor, as in “Mayor Sam · Lumen Bay · population 198” |
Each floor is just as wide as its homes need, and the floors with the most homes go at the bottom, so every building gets narrower as it rises.
Milestones
Your population counts every task you've ever finished. Each time you hit a milestone, your city gains something new, and it's yours to keep.
| Population | Your city gains |
|---|---|
| 10 | Street lamps on every corner |
| 25 | A park at the south end of town |
| 50 | A fountain in the park, which becomes the town square |
| 100 | A train line looping round the city |
| 250 | A harbour with a pier, a lighthouse and boats |
| 500 | A stadium with floodlights |
| 1,000 | A bridge across the harbour to a second island |
To see what's been built and how far you are from the next one, open your city and click Milestones. Each milestone gets celebrated once, and adds a new chapter to your city's Story.

Calm by design
Your city only ever grows.
- What's built stays built. Un-ticking or deleting a task never takes anything away.
- There are no streaks, points or penalties. A quiet week is just a quiet week.
- Rewards are just for your city. You get every feature of TodoCity from day one.
Explore it
In full screen, your city sits in the bottom-right corner and glows whenever someone moves in. Click it to open the city in 3D.
- Drag to look at it from any angle, scroll to zoom, and double-click to reset the view. The arrow keys, +, − and 0 work too.
- Point at a window to see its task, and whether the home is empty, being readied or overdue, or when someone moved in. Point at a building to see how many of its homes are lived in and how many are still empty.
- Click a building and TodoCity glides over to it and opens that project. Click the houses to see tasks that aren't in a project, or a plot to see Someday.
- Story walks you through how the city works, one page at a time.
- Look back over the last 7 days, 30 days or All time to see new residents, your population, your tallest tower, finished projects and your busiest moving day.
