Screen time you earn — not screen time you fight over. QuizLok blocks the apps that eat your day and gives them back only after you pass a short, AI-generated quiz. Learn something, unlock something. It's that simple. HOW IT WORKS 1. Pick topics — math, science, history, or your own custom subjects. 2. Block apps — choose what stays locked until a quiz is passed. 3. Take a quiz — fresh AI questions every time, adapted to the right level. No memorizing answers. 4. Earn screen time — pass, and your apps unlock for the time that was set. FOR FAMILIES Stop being the bad guy. Set the rules once and let QuizLok enforce them. • Choose which apps are locked and how much time a passed quiz earns • Steer what your child studies • Weekly report cards show what they're actually learning • A bypass-proof setup with no easy off switch — nothing kids can quietly get around FOR YOU Not a parent? QuizLok works just as well on yourself. • Turn doomscrolling into study time • Prep for a cert or exam while you earn your break • Built for anyone who knows willpower runs out — future-you can't bargain with present-you WHY IT WORKS Willpower isn't the answer, and neither is another timer you'll just tap "ignore" on. QuizLok puts a small, useful task between you and the apps you're trying to use less — so the time you spend is time you chose.

Verdict
The clearest difference is rating: QuizLok at 4.9 against StudyLock's 4.0. QuizLok also leads on update cadence (every 8 days vs monthly) and ratings volume (14 vs 2). StudyLock's advantage is monetization model (free with in-app purchases vs subscription). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. StudyLock sells 3 in-app purchases, starting at $1.99 per 7 days and QuizLok sells 2 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
QuizLok holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: QuizLok has 14 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
StudyLock ships an update monthly, QuizLok every 8 days. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
