LightsOn: Move to Build a City

LightsOn turns your real-world activity into a living city. Every active calorie you burn — walking, running, working out, or just moving through your day — flows straight from Apple Health into your city's battery. Keep it charged and the lights stay on: new residents move in, the streets come alive, and your town grows. Let the battery run dry and the city goes dark — residents pack up and leave. It's a cozy, idle city builder where YOU are the power plant. HOW IT WORKS • Your active energy from Apple Health charges the city automatically — no manual tracking, it just works in the background. • Lights on → residents arrive and your town thrives. • Battery empty → blackout, and people start to leave. • Real workouts earn bonus credits to spend on upgrades. • Build a factory that produces parts for bigger and better upgrades. • Your city keeps running while you're away — come back to see how far it grew. WHY YOU'LL LOVE IT • A real reason to move: every step and workout has a visible payoff. • Relaxed, no-pressure idle gameplay — perfect for short bursts. • A charming isometric city that's entirely yours to grow. • Clean, dark design that's easy on the eyes. FREE & PRIVATE • Completely free — no ads and no in-app purchases. • No tracking and no data collection — your health data never leaves your device. Move more, build more. How big can your city get?
