ReactQuest
Predict the reaction — a chemistry game for ages 15–18. Forecast an outcome, then a real model proves you right or shows you why not — stoichiometry, equilibrium, kinetics, acids & bases, gas laws, periodic trends, thermochemistry, and redox. Predict-observe-explain, on-device.
▶ Play it nowBuilt for sittings of about 25 minutes on the screen. That is our design budget, not a measurement.

What's inside
Learning goal
Predict the reaction — a chemistry game for ages 15–18. Forecast an outcome, then a real model proves you right or shows you why not — stoichiometry, equilibrium, kinetics, acids & bases, gas laws, periodic trends, thermochemistry, and redox. Predict-observe-explain, on-device.
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 Sabina — on-device AI, no data leaves the device.
How ReactQuest 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
ReactQuest 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.
