Your apps stay locked until you can do the math. Times Up blocks the apps you open without thinking (social, video, games) and unlocks them only when you answer a quick math quiz. Each quiz buys a set window. When the timer runs out, everything locks again. WHY A MATH GATE BEATS A TIMER A "5 more minutes" button takes half a second and no thought, which is why you always tap it. A math quiz takes fifteen seconds and real attention, and that is long enough to notice you never meant to open the app. A lot of sessions end right there, before the unlock. IT GETS SHARPER AS YOU DO Times Up scores every problem you see and weights the next quiz toward what you keep missing. The facts you are slow on come back more often. The ones you have nailed return on a spacing schedule so they stay sharp. Everything runs on the device, so questions are instant. TEN TIERS PER OPERATION Addition, subtraction, multiplication, division, and missing-number puzzles ("? x 8 = 56"). Ten tiers each, climbing as your accuracy holds. Mental arithmetic is a real skill that most of us quietly lost to calculators, and this rebuilds it in the gaps you were going to waste anyway. YOU SET THE RULES Choose which apps to block, right down to whole categories. Set quiz length from 3 to 10 questions and pick how long each unlock lasts. A 4-digit PIN protects your settings from your own weaker moments. WHAT YOU SEE Overall accuracy and 7-day trend, tier badges for each operation, a Needs Work list of the problems you keep dropping, and a daily log of every quiz. PRIVACY BY DESIGN Every answer and score stays on your device. No cloud, no accounts, no advertising IDs, no ads. REQUIRES iOS 17 or later. Apple Family Controls permission, granted on first launch. SUBSCRIPTION Times Up Premium unlocks the full app, including app blocking, the adaptive quiz engine, and your stats. There is no free version. Premium is offered as a weekly or yearly auto-renewing subscription, and current pricing is shown in the App Store before you purchase. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions auto-renew unless turned off at least 24 hours before the end of the current period.

Your phone unlocks over 150 times a day. What if each unlock made you smarter? NumLock turns your screen time into brain time. Before you can open your blocked apps, solve a set of mental math problems. It takes seconds, keeps your mind sharp, and adds just enough friction to break the mindless scrolling habit. HOW IT WORKS Choose which apps to block. When you try to open one, NumLock presents math problems you solve on a number pad. Get them all right and your apps unlock for your chosen grace period. Simple, fast, and surprisingly satisfying. ADAPTIVE DIFFICULTY NumLock starts easy and gets harder as you improve. The 25-level system tracks your accuracy and speed, automatically adjusting to keep you challenged. Start with basic addition. Work your way up to multi-step equations, percentages, and large multiplication. You'll be amazed how fast your mental math improves. GRACE PERIODS THAT FIT YOUR LIFE After solving, your apps stay unlocked for a window you choose — 5 minutes for a quick check, 30 minutes for a balanced session, 1 hour for extended use, or until midnight for a full day off. When time's up, the lock comes back automatically. STREAKS AND STATS Build a daily streak by solving at least one session per day. Track your accuracy, average solve time, current level, and total problems solved. Watch yourself get faster and sharper over time. Your best streak is always recorded — can you beat it? DESIGNED FOR ADULTS NumLock isn't a parental control. It's a tool for people who want to take back control of their own screen time while training their brain. Think of it as a gym membership for your mind that activates every time you reach for a distraction.

Verdict
The clearest difference is iOS requirement: NumLock at 17.0 against Times Up's 26.0. On price, ads, in-app purchases and device support there is nothing between them.
