What's New in LightsOn

3.2.0

October 19, 2026

• Look inside the Restaurant: an open kitchen at the back, the dining room with counter, booths and terrace up front. Every cuisine style cooks in its own kitchen — Classic, Sushi, Pizza or Burger. While it’s open, the fire burns and guests come in waves; after closing time it stays dark and quiet. • Factory boost starts by itself: choose a charge level, and once your battery climbs back above it, the boost switches on automatically — the perfect partner for the battery limit. • New houseplants for your homes: a chili plant and a palm. • New weather: the hurricane, the rarest storm of all — sideways rain, flying leaves and lightning strikes that shake the city. And when it rains, your residents now open their umbrellas. • A rare sky: roughly every five days there’s a sunny day with a glowing sun, and a clear night with the Milky Way stretching across the sky. • Bugfixes and various improvements.

Don’t not move.

I really like this game bc it keeps me honest about my fitness. I check in every day multiple times. I lost my streak bc i didn’t move 300k cals that day. Rest day. So move a little if you want to keep your streak!

Response from developer

Thanks for the review. Did you check that you had made 300kcal that day? You have to make at least 300kcal every day for the streak to count, just opening the app is not enough. You can also build the reserve depot and use streak shields for days where you can’t get your streak. If you still have problems you can contact us, and we will figure it out.

LightsOn

Manchmal bisschen buggy und die Trainings werden nicht nicht ganz gezählt (benutze Mi Fitness und ich glaube das Xiaomi Band 8). Ich bekomme dann nur 30 Credits, obwohl ich 620 Kalorien verbrannt habe,
aber eigentlich wirklich cozy!

Response from developer

Danke für das Review. Das mit den Trainings kann passen, da LightsOn nur auf die Aktivitätskalorien geht, nicht auf die Gesamtkalorien. Die 620 bei dir sind vermutlich die Gesamtkalorien. Bei Fragen dazu kannst du uns gerne direkt kontaktieren.

Großartiges Spiel!

Als ehemaliger Sim City Fan war ich super neugierig als ich von LightsOn gehört habe. Ich habe im Sommer angefangen, dieses Spiel zu spielen und ich liebe es. Es drängt sich nicht auf, es macht aber immer wieder Spaß, sich Schrauben und Credits anzusparen und dafür coole Sachen in der Stadt zu machen. Man kann sich auch eine Strategie für die Stadt überlegen (Akku ausbauen, Einwohner bekommen, Stromkosten senken, usw.)- muss man aber nicht, da es kein „richtig“ oder „falsch“ in diesem Spiel gibt. Und genau das macht es so angenehm! Und selbst falls man es mal verpasst hat dranzubleiben und Einwohner abhauen, bricht keine Welt zusammen – man kann jederzeit ganz entspannt wieder einsteigen.
Die eine oder andere Extrarunde habe ich deswegen schon um den Block gedreht oder mich noch einmal extra aufs Rad gesetzt, um den Akku noch ein bisschen weiter zu laden ;-)
Die Spielidee ist simpel und mir fällt spontan kaum eine bessere Idee ein, wie man die Motivation zu Sport und Bewegung noch besser miteinander verbinden könnte. Es gibt viele Apps, die gegen viel Geld genau das versuchen zu erreichen und jetzt kommt so eine kleine App, die nicht einen Cent verdienen möchte und schafft das was andere Apps für hunderte von Euro bei vielen Menschen nicht schaffen. Das ist schon bemerkenswert. Vielen, vielen Dank an den überaus sympathischen Entwickler und bitte weiter so!

Creator is responsive on Reddit

Enjoy this app because it motivates me by gamifying moving my body more. And love how the creator helped me instantly on Reddit when I didn’t understand a few features.

Response from developer

Thanks for the review. Important is that you connect the peloton app with apple health, so that LightsOn can see your workouts. And if you have an apple watch, every movement like doing the dishes will charge your battery. You can also manually log workouts in apple health and LightsOn will pick it up. The beginning should be really easy, like a walk around the block is enough to charge the battery. You can also contact me directly and I can help you how you can integrate your workouts so that they count.

AMAZING … BUT

This app makes working out and logging calorie counts so much more fun! Incredibly motivating. Only thing I noticed is that today I walked over 3k steps while out and about and none of it shows (but does appear in my health app)

Response from developer

Thanks for the review! This was a bug that was resolved in Version 2.4.0 which is out now. If you update the app it should not happen. Don’t worry, your steps will still count.
