Practice Tool

Android Prep is a browser-based interview practice tool: 41 chapters and 401 flashcards from The Android Interview Book. All chapters and flashcards are free; free users see ads. Content, question order, and scoring are study aids and may change as the product improves.

Premium

Premium removes ads only. It does not lock any chapter or flashcard. Plans and prices are shown in the app; sign-in with Google or an email link is required to start or restore Premium.

Renewal and Cancellation

Plans renew automatically every month, six months or year, matching the plan you pick, and are charged to the payment method used at checkout until you cancel. Cancel anytime by emailing contact.gangwar@gmail.com before the next renewal; Premium stays active until the end of the period you already paid for. Deleting your account does not cancel a renewal.

Minimum Age

You must be at least 13 years old to use Android Prep. If you are under 18, you need a parent or guardian's consent.
