Meet the cast
LetterLoops is a little band of animal friends who help the youngest writers MAKE letters and numbers — the shaping you feel in your hand that helps reading grow. Squiggle the snail is the hero; the cast are Squiggle's friends. Everything is spoken and playful, with no wrong answers — a wobbly letter is just 'let's shape it together.'
Squiggle
The whole-letter stroke — a snail whose slow, steady trail IS the letter taking shape.

Whorl
Curves and loops — a chameleon whose curled tail IS the round parts (c, o, e, s).

Chirp
Say-while-you-make — a songbird who sings each letter's sound as you shape the stroke.

How LetterLoops 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
LetterLoops 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.
