DioramaForge
Build a biome diorama for ages 9–14: place the plants and animals so the food web actually holds — a producer to catch the sun, prey for every predator, and everything where it really lives — then defend your choices like a curator. On-device; nothing leaves your device.

Meet the cast
DioramaForge's cast each embody one part of the food web; naturalist Sylva asks “where does the energy come from, and who eats whom?” — nothing eats without something being eaten, so you build the web from the sun up.
Sylva
the food web — build from the sun up: a producer, the animals that eat it, and the recyclers that close the loop
Sol
Producers — plants and algae that turn sunlight into food; every web starts here
Browse
Herbivores — the grazers and browsers that eat the plants
Fang
Carnivores & omnivores — the hunters, and how much prey a web must have to support them
Cycle
Decomposers — the worms, beetles, and microbes that return dead things to the soil

How DioramaForge handles your kid's data
- ✅ All progress, settings, and AI-generated content stays on the device
- ✅ No analytics, no tracking, no third-party SDKs
- ✅ Free — no ads, no in-app purchases
