MathGate
Read full descriptionHide full description
Pick the apps that eat your day. MathGate puts a math problem in front of them. Tap one and you get a question instead of a feed. Solve it and the app opens for as long as you chose. Close it and walk away, and MathGate counts that as a win. FREE Three problems per session, across all five subjects. MATHGATE PRO, A ONE TIME $2.99 PURCHASE Set anywhere from 1 to 10 problems per session. Choose how long an unlock lasts: 15 minutes, 30 minutes, 1 hour, or 2 hours. Pick your subjects: fractions, long division, algebra, percentages, geometry. HOW THE PROBLEMS WORK You get three tries. Miss the first and you get a hint. Miss again and MathGate shows you the answer. One skip per session, so waiting out the timer is not a free pass. WHAT IT TRACKS Day streak and best streak, with one grace day a month so a single slip does not wipe the board. Problems solved today and your accuracy. A running count of the times you hit the gate and chose to walk away instead. Optional evening reminder to keep the streak alive, and a Sunday recap of the distracted opens you dodged that week. Everything stays on your iPhone. No account, no sign up, no server, no analytics. MathGate cannot see which apps you picked.
MindLock

Turn mindless scrolling into a moment of thinking. MindLock puts a short quiz or word game between you and your most distracting apps. Get it right and they open. Get it wrong and they stay locked for a 10-minute cooldown. No willpower needed, just a few seconds of real thought before the feed. HOW IT WORKS 1. Choose the apps and websites that eat your day. 2. Open one and the lock screen stops you. Tap it to start a challenge. 3. Pass, and your apps open for as long as you set, from 30 minutes to 3 hours. 4. Time's up? They lock again on their own. A countdown on your Lock Screen and in the Dynamic Island shows how long you have left. PICK YOUR CHALLENGE • Quiz: quick rounds on up to 5 themes, like Math, Logic, Geography, History, Animals, Movies and People. • Spelling Bee: hear a word, then type it letter by letter. Exact spelling only. • Word Collapse: start with a long word and remove letters to make a shorter real word, again and again. Hit a dead end and you're locked out. • Random: a surprise every time. Mixed themes, spelling words or a Word Collapse puzzle. SET THE FRICTION Five levels, from Easy to Perfect Run. Easy asks for 3 correct answers out of 5, with hints. Perfect Run asks for 15 out of 15, with 10 seconds per question and no second chances. SHORTCUTS HAVE A PRICE Really need an app right now? Use an emergency unlock straight from the lock screen. You get a few a day, and each one adds an extra question to your next quiz. WATCH THE HABIT CHANGE • Streaks, passes and correct answers at a glance • Damage to Big Tech: the ad money your skipped scrolls never made • Home Screen widget with your reps and streak PRIVATE BY DESIGN MindLock is built on Apple's Screen Time.

FREE TO START Create as many locks as you like, with Math and Logic quizzes on Easy, Medium and Hard. MINDLOCK PRO • Extreme and Perfect Run difficulties • Every quiz theme beyond Math and Logic • Spelling Bee, Word Collapse and Random • Advanced metrics: knowledge level, accuracy, strongest themes, recent games and a Screen Time report with the apps to lock next Pro is available as a monthly or annual subscription.
