WHY OFFLINE
All lesson content is shipped inside the app — no streaming, no fetching. Use it on a plane, a Chromebook with restricted Wi-Fi, or anywhere with no signal.

WHY CS++
We've taught AP CSP online at csplusplus.com to teachers and students across the United States. This app distills the full course into a focused study tool — same content, same alignment to the 2025-26 College Board CED, packaged for the device you carry every day.

VIDEOS NOT INCLUDED
The course videos that accompany each lesson on csplusplus.com are not bundled in the app (to keep the download small and fully offline). Each lesson includes a "Watch on csplusplus.com" link that opens the corresponding video in a browser.

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 inline checks. The full unlock is a one-time $9.99 purchase that unlocks all 11 units forever, with no subscription.
