Meet your mentor

Every Spark & Anvil app has a friendly mentor character that demonstrates, praises, and patiently scaffolds learning. On-device AI personalizes the mentor's responses to your kid's progress — never connecting to a server, never collecting data.

WeatherForge is a meteorology and storm science lab for ages 9-14 where players build weather instruments, track real storms using live weather data, predict tomorrow's weather, and simulate the forces behind Earth's most powerful phenomena — hurricanes, tornadoes, thunderstorms, and blizzards.

Distributed-narrative cast

Meet the cast

WeatherForge teaches meteorology as a **family of atmospheric processes** — pressure systems, air masses, fronts, storm formation, water cycle, and forecasting reasoning.
