ABC Zoo is a free learning app for toddlers and preschoolers, covering the alphabet, letter sounds (phonics), numbers, spelling, letter tracing, shapes, colors, and simple sentence building.
ABC Zoo runs entirely offline. There's no account to create, no ad network, and nothing tracked or sent anywhere — it works the same on a plane, in a car with no signal, or at home. Progress (stars and stickers) is saved only in your own browser's local storage on your device.
It's also installable as a Progressive Web App, so it can sit on a home screen and open like a native app without an app-store download.
Ten activities in total: Letters, Guess the Letter, Numbers, Phonics, Build a Word, Colors & Shapes, Match It, Trace It, Make a Sentence, and a sticker-reward system that unlocks as kids play.
