A new chapter for LockQuiz
LockQuiz is
now LockFeed.
Current LockFeed 1.3 brings LockFeed’s full quiz library and onboarding to the same app you know as LockQuiz. Choose your apps, pick your quiz, and earn a little time before your next scroll.

The full LockFeed library
More ways to make the pause count.
The full library has 14 quizzes: guitar fretboard notes; SAT, ACT, MCAT, LSAT, and US bar practice; UK driving; UK citizenship; US citizenship in multiple-choice and typed formats; world flags; vocabulary; chess; and art history.
- A guided setup with a quiz demonstration, app selection and unlock duration.
- No account or ads. Upcoming 1.4 analytics will be optional.
- Local practice history and progress. Practice mode never unlocks apps.
Current LockFeed 1.3 includes five successful real app unlocks, then requires a US$4.99 one-time lifetime purchase for further unlocks. Standalone quiz practice requires lifetime purchase immediately; the onboarding demonstration remains free. There is no subscription, and Apple displays your localized price before purchase.
Upcoming 1.4 keeps the same access policy and adds optional analytics plus consistent gift offers for eligible new installations. Existing lifetime access remains recognized. See version-specific support and the privacy policy for details.
If you still have the SAT-only LockQuiz 1.0 release, your current setup instructions are here. The current LockFeed version already includes the expanded library.
Exam practice is not an official test or a score guarantee. Sources and applicable content credits are available in the app.
