VowelTots
Meet the five Vowel Sisters — for ages 3–5. Press to hear a little word, then tap the sister whose sound you hear in the middle: cat is Ava, dog is Ollie. Then watch Magnet-E work her magic — cap becomes cape, and the sister sings her name! No reading needed, no score, no rush. On-device, no accounts.
