LightsOn: Move to Build a City

Your steps & workouts run it

Free · Designed for iPhone. Not verified for macOS.

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?

• New: the Bank! Deposit your credits and they earn interest every day — the higher you upgrade the bank, the more it pays out. Withdraw any time, and give it your own look: Art Deco, Western or Futuristic, each in your favorite color. • Look inside the Battery: the cell racks light up as far as your battery is charged, and you can watch the power flow through the cable ducts. At higher levels it grows a second and third hall. New for the battery: the Futuristic energy cell that glows at night. • Factory boost with a battery limit: choose a charge level, and the boost switches itself off before your battery runs too low — even while the app is closed. • New widgets for your streak: “Activity Streak” and “Battery & Streak” for the Home Screen, Lock Screen and Apple Watch. • Streak protection from the Reserve Depot now costs a third less energy — plus bugfixes and various improvements.
