Meet the cast
RhymeReef is an under-the-sea band of sound-friends who help little ears hear the music inside words — rhyming, clapping the syllable beats, catching the first sound, and spotting the one that sounds different. Rhyma the dolphin is the hero. It's all by ear (no letters yet), sung and playful, and a missed sound is a friendly retry.
Rhyma
Rhyme — a singing dolphin who calls back a word that ends the same (cat → hat); matching end-sounds IS rhyme
Read chapter →
Clappa
Syllable segmentation — a clappy crab who claps the beats in a word (el-e-phant = 3 claps); clapping the beats IS syllables
Read chapter →
Sula
Onset / first sound — a gentle seahorse who catches the first sound (/s/ in sun); the beginning sound IS onset
Read chapter →
Finn
Sound discrimination — a quick fish who spots the word that sounds different; hearing the difference IS discrimination

How RhymeReef handles your kid's data
- ✅ All progress, settings, and AI-generated content stays on the device

- ✅ 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
RhymeReef 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.
