TinkerForge
Change one line, predict the diff. Read a little program that stamps shapes — a row of circles, a growing trail, a grid, some rain — and see what it draws. Then one line changes (a count, a shape, a coordinate, an operator, an if’s threshold): predict the new picture before you run it. Real tinkering is a small change, a careful guess, a look — not button-mashing. A read-before-you-run lab. Ages 9–14.

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.

Meet the cast
TinkerForge's tinkerers change one thing at a time, so you can say exactly what each line does.
Tweaky
(The one you teach) - changes five things at once and can't say which did what — you teach one change at a time
Diffy
finds the one changed line
Randle
scatters things anywhere inside a range

Question kits
16 curriculum-aligned kits × 25 questions = 400 questions per app, mapped to recognized standards.
On-device AI mentor
FoundationModels-powered hints, feedback, and adaptive difficulty — all running locally.
How TinkerForge 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
- ✅ No personal information collected from children — in line with COPPA (updated by the 2026 FTC amendments)
- ✅ Parental controls + session limits + content filters built in
TinkerForge 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.
