ConveyorForge
A factory where the maths IS the belts. Threefer turns 3 ore into 2 plates every 4 seconds; how many machines keep up with the ore? Add too few and the belt backs up; too many and one sits idle. Find Bottleneck Bea — the slowest stage — and fill the order exactly. Eight levels, each with a measured weight. Ages 9–14.
Built for sittings of about 20 minutes on the screen. That is our design budget, not a measurement.
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
Every machine is a ratio with a personality. Threefer turns 3 ore into 2 plates; Gearwin presses 2 plates into a gear; Boxley packs 4 gears into a box; Snipper cuts 5 into 3; and Bottleneck Bea is always the slowest step - the one to find first.
Threefer
(Mentor) - turns 3 into 2 every 4 seconds
Gearwin
Presses 2 plates into 1 gear every 2 seconds
Boxley
Packs 4 into 1 box every 6 seconds
Snipper
Cuts 5 into 3 every 6 seconds
Bottleneck Bea
The slowest stage - a line is only as fast as she is

Learning goal

FoundationModels-powered hints, feedback, and adaptive difficulty — all running locally.
Mentored by Threefer — on-device AI, no data leaves the device.
How ConveyorForge 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
ConveyorForge 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.
