Q-City: City Builder Sim
Offline isometric city sim
Free · Designed for iPad. Not verified for macOS.
From a single road to a metropolis.
Q-City is a classic isometric city-building simulation. Lay roads, zone residential, commercial and industrial land, hook up a power plant and a water tower, and citizens start moving in and building. As jobs, services and the environment improve, low-rise homes grow into dense high-rises, and your city climbs from Outpost to Village, Town, City, Metropolis and beyond.
WHAT YOU GET
- Tile-based isometric city building. Pan with one finger, pinch to zoom
- Residential (R), Commercial (C) and Industrial (I) zones that grow from density 1 to 3 based on demand and surroundings
- A power grid: coal, wind, solar, nuclear and fusion plants. Electricity flows along roads and buildings
- A water network: water towers, pumping stations and treatment plants. Dense growth needs water
- 18 facilities: police, fire station, elementary school, hospital, university, city hall, parks, plaza, stadium and more
- 6 milestones: every population threshold pays a bonus and unlocks new facilities
- Budget and taxes: set residential, commercial and industrial tax rates separately and read the monthly report
- 12 data overlays: power, water, pollution, land value, crime, traffic, growth potential, and fire / police / health / education / leisure coverage
- Day/night cycle: watch the lights come on at dusk
- Disasters: fires, earthquakes, meteors and tornadoes — trigger them yourself if you dare
- An advisor that flags power shortages, rising crime, unemployment and more
- 3 save slots plus monthly autosave, and JSON export/import to back up a city or move it to another device
