SolfaPals
Sing do-re-mi with Octavia the octopus (ages 6–8): sing a solfa step and Octavia floats to your note, then a limb lights up when you hold it — with Curwen hand signs and a music staff that peels back from dots to real notes. Every little song is sung in YOUR key. On-device — your voice never leaves the device, nothing is recorded.

Meet the cast
SolfaPals is a gentle singing app for ages 6 to 8. Octavia the octopus floats to the note your child sings and lights up a limb for each step of do-re-mi, Bluma the whale sings low, Pico the little fish sings high, and Reef slowly turns dots into real written notes. Illustrated stories are on the way.

How SolfaPals 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
