448 apps

Gentle, tap-and-play apps for our youngest (Pre-K & Kindergarten) — big buttons, audio-first, no reading required, and no way to get it “wrong.”

A happy toddler playing with big, bright building blocks on the floor while two round, cartoon-cute creatures cheer along.

Early-elementary apps (grades 1–3) — hands-on manipulatives with short, read-aloud questions. Big-kid feel, gently supported.

An early-elementary child building with colorful wooden cubes and counting tokens on a table, guided by a friendly cartoon helper character.

The tween core — full lessons, characters, and practice across every subject. Tap a subject to open it.

A focused tween working a puzzle with pencil and paper, paper fraction strips, a chess piece and a cipher dial, beside a friendly cast character.

Numbers, fractions, geometry, and proof.
