Lock In – Study & Move

Turn 6 seconds of studying into 30 minutes of scrolling you earned. Flashcards or phone-counted reps unlock your apps. 25+ subjects, 1,500+ questions, all offline.

Earn your screen time by learning — or moving — not doomscrolling.

Lock In blocks your most distracting apps — Instagram, TikTok, games, whatever pulls you in — and puts a quick challenge in front of them. Answer a few flashcards on a subject you choose, or knock out a set of reps, and your apps unlock for a set time. When the timer's up, they lock again. Every unlock builds a daily streak you'll fight to keep.

HOW IT WORKS

1. Pick the apps to block and how you want to earn them back.
2. Open a blocked app → a challenge appears instead.
3. Answer correctly, or finish your set → your apps open for 15 to 120 minutes — you choose.
4. Keep your streak alive and watch it compound.

TWO WAYS TO EARN YOUR SCROLL • Study — flashcards on a subject you pick. 25+ real subjects built in: SAT vocab, biology, chemistry, Spanish, coding, US history, psychology, world capitals, and more. 1,500+ curated questions that work fully offline. • Move — put the phone down and do a set. Your phone counts the reps with its motion sensors, so push-ups, squats and jumping jacks all work. You choose how many reps it takes.

WHY IT WORKS • Friction where you need it — a 6-second gate beats endless willpower. • Streaks that stick — a fire streak, milestones, and a shareable study-wall card. • Private by design — no account, no ads, no tracking; your progress stays on your device.

Free — ten unlocks a day, and they reset every midnight.

Lock In uses Apple's Screen Time (Family Controls) so you can block and unlock your own apps.
