Special Interest
GrowForge
Grow a virtual garden powered by real weather data, design plant experiments, and discover the science of photosynthesis, genetics, and ecosystems — bridging the digital and natural worlds.
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.

#FFA726 GrowForge is a plant science lab and virtual garden powered by real weather! Grow plants in a garden that responds to your actual local weather, look at plant cells under a digital microscope, design science experiments to find out what makes plants thrive, and even track a real garden alongside your virtual one.
Distributed-narrative cast
Meet the cast
GrowForge's 5-character cast embodies garden-craft primitives — seed-and-planting listening (Tuck), water + irrigation patience (Drip), photosynthesis + cell-level biology (Glow), container + apartment gardening access (Pot), and observation + plant-doctoring patience (Vigil). Sprig frames each primitive; cast embodies them at kid-and-windowsill scale (NEVER suburban-backyard-default mascotization). Nature-deficit + privilege gate enforced: cast NEVER assumes access to outdoor space, free time, or supplies; Pot's structural presence from kit 8 onward names apartment-windowsill / urban / community-plot as PEER gardening contexts (NOT lesser-than backyard); Pot's catchphrase 'a windowsill is a garden too' is load-bearing; static-response gating for 'real gardeners need a yard' / 'apartment kids can't garden' prompts NEVER reaches FoundationModels (Sprig surface filter). Hands-on-care framing throughout (NOT extractive harvest-and-consume framing).

What's inside
Virtual Garden
Plant seeds, water them, and watch them grow over real time. Your local weather (sunshine, rain, temperature) affects how your plants do! Check on your garden e
Botany Lab
Zoom into plant cells under a digital microscope. Identify the cell wall, chloroplasts, and other parts. Learn how photosynthesis turns sunlight into food for t
Experiment Designer
Set up controlled experiments to test what plants need. Change one variable at a time -- like amount of water or sunlight -- and record what happens. Your resul
Real Garden Tracker
Growing a real garden too? Take photos of your real plants and track their progress right next to your virtual garden. Compare how real and virtual plants grow!
Mentored by Sprig — on-device AI, no data leaves the device.
How GrowForge handles your kid's data
- ✅ All progress, settings, and AI-generated content stays on the device
- ✅ No analytics, no tracking, no third-party SDKs
- ✅ No ads, no in-app purchases — you pay once
- ✅ COPPA compliant under the 2026 FTC amendments
- ✅ Parental controls + session limits + content filters built in
GrowForge 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.
