HumTots
Find your singing voice with Hummy the hummingbird (ages 3–5): hum along and Hummy floats to your note, then lands on the flower when you hold it. Every little song is sung in YOUR key, so it always feels just right. On-device — your voice never leaves the device, nothing is recorded.
▶ Play it nowBuilt for sittings of about 10 minutes on the screen. That is our design budget, not a measurement.
Meet your mentor

How HumTots 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
For you, the grown-up
The grown-up side of HumTots on Spark & Whetstone, our free site for grown-ups: Singing with a Child. Humming back a note is the first step; the course says why the range matters.
It also tells what HumTots teaches in a short course of its own.
