WHY OFFLINE
The bundled Java runtime executes code locally on your device. The lesson content is shipped with the app — no streaming, no fetching, no slow connections. Use it on a plane, a school Chromebook with locked Wi-Fi, or anywhere with no signal.

WHY CS++
We've taught AP CSA online at csplusplus.com to teachers and students across the United States. This app distills the full course into a focused practice tool. Same content, same alignment to the 2025-26 College Board CED, same Java subset — packaged for the device that's always in your pocket.

PRIVACY
No account creation. No sign-in. No analytics or tracking. All progress lives in app storage on your device. No data is sent to our servers.

THE PURCHASE
The free tier covers Unit 1 — enough to evaluate the lesson format and the inline Java runtime. The full unlock is a one-time $9.99 purchase that unlocks all 11 units forever, with no subscription.

WANT THE EDITOR ALSO?
For a free-form Java environment with multi-file projects and a templates menu, see our companion app CS++ Java IDE — same Java runtime, just an editor instead of a course.
