## What is TTLocker?

TTLocker puts a short quiz between you and the apps you open on autopilot.

Pick the apps you want to use less. When you open one, TTLocker steps in first. You can close it, or answer a few questions to get 10 minutes. A wrong answer doesn't count against you. You just get a new question.

Each app also gets a daily limit. Keep it fixed, or let it drop 10% a day until it reaches a minimum you choose. Once you've used it up, the app stays locked until tomorrow, with one chance a day to quiz your way to a few extra minutes.

Choose what you'd rather be learning: flags, capitals, mental math, vocabulary, history, art history, chemical elements, general knowledge and US road rules, plus chess, xiangqi, gomoku and go puzzles. You decide how many questions it takes, from 1 to 10.

The Usage tab shows your screen time, pickups and notifications, and which apps take up most of your day.

Everything stays on your iPhone. There's no account and nothing gets uploaded. TTLocker runs on Apple's Screen Time, so it needs Screen Time permission to work.
