CardGate turns your phone's distractions into study motivation. Pick the apps that waste your time, bring your flashcards (or let AI generate them), and your phone won't open those apps until you pass a quiz. BUILT FOR • Students grinding Anki for exams (USMLE, MCAT, A-levels, Abitur, bar prep) • Language learners building vocab in Spanish, Japanese, German, and more • Anyone trying to cut screen time — but tired of apps that just nag HOW IT WORKS 1.

ABOUT FAMILY CONTROLS (SCREEN TIME) CardGate uses Apple's official Family Controls / Screen Time APIs to block apps. You'll be asked to grant permission once during setup. Apps you select are tokenized by Apple — CardGate never sees the actual list of apps you've installed and never reads your screen. SUBSCRIPTION TERMS Premium is offered as Weekly, Monthly, Yearly auto-renewable subscriptions and a one-time Lifetime purchase.
