Special Interest
WeatherForge
Build weather instruments, track real storms, predict tomorrow's weather, and simulate the forces behind Earth's most powerful phenomena.

Meet your mentor
Every Spark & Anvil app has a friendly mentor character that demonstrates, asks, 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.
Mentored by Gale
#FFA726 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.
Characters who teach
Meet the cast
WeatherForge teaches meteorology as a family of atmospheric processes — pressure systems, air masses, fronts, storm formation, water cycle, and forecasting reasoning.

Question kits
16 curriculum-aligned question kits, 400 questions in all, mapped to recognized standards.
On-device AI mentor
FoundationModels-powered hints, feedback, and adaptive difficulty — all running locally.
Mentored by Gale — on-device AI, no data leaves the device.
How WeatherForge 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
- ✅ No personal information collected from children — in line with COPPA (updated by the 2026 FTC amendments)
- ✅ No chat with strangers — play-together rooms use a short code and preset emotes, never typed messages
WeatherForge runs on ForgeKit — the open-source Swift Package Manager framework that powers every Spark & Anvil app. ForgeKit ensures consistent accessibility, COPPA compliance, and design language across the portfolio, so your kid's progress and preferences feel coherent across every app they touch.
