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?

It’s very nice and simple. Add a steps tracking feature.

By adding a steps tracking feature you might keep users like myself more involved with the app. I workout 3 times a week but I also walk 2-3 times a week but not necessary with the workout app just lots of steps throughout the day.

Thanks for the review. Your steps will already charge the battery even if you don't record them as a workout. All your daily activities count like steps or climbing floors. It's basically all your activity calories. But only recorded workouts give extra credits.However displaying the steps per day could be interesting as a separate statistic.

Good concept, needs to go further

The idea of this game is fun and it’s nice that it keeps the user thinking about activity. The issue is that the game needs to go a bit more in depth. It doesn’t really feel like you’re building a city because there are not many unique things you can add to customize and make it feel like your own. If you could add attractions that also draw power but improve happiness that would be cool. Like a museum or a zoo or a park. Also it would be cool if the people who live in your city could have a little individuality such as a list of the residents names and maybe a generated fact or two about them. Those suggestions would be great ways to expand the idea to be less repetitive and more customizable without making it too complicated. Thanks for reading, I hope you consider implementing some of this feedback.

Thanks for the feedback. These ideas are great and many features will be added in the future (while still keeping the game simple enough). Another fun idea would be implementing themes where you could have a scifi or medieval city. Until then save up some credits.

I realize this is a pretty simple game right now, but it’s a fantastic concept, and has actually made a bit of a difference in my daily routine. Can’t wait to see how it evolves. Just expanded my town and I have to admit, I care about keeping it lit up!

I am obsessed with this app. So much fun to see my effort translated into this clever little sim world. Very fun…but I can also see how keeping the lights on could be challenging as the city gets bigger. Excited to see how the app evolves over time. Big fan!

- A new building: the Fitness Center! It grows in 50 stages from a tiny studio into a glass temple with a rooftop pool — and every stage boosts your workout bonus credits, up to double when fully built. It can even earn you fractions of bonus credits — the statistics show them with one decimal place. - Bugfixes and various improvements.
