Lookup quietly hands that time back — it blocks the apps that steal your focus, sets you a daily goal, and shows you exactly where your hours go. Less phone, measurably better. BLOCK WHAT DISTRACTS YOU Choose the apps that pull you in, and Lookup steps in the moment you reach for them. Set lasting limits or start a one-tap block when you need to focus right now. SET A DAILY GOAL Pick a target for your screen time and watch your real progress against it, day by day. No guilt — just a clear picture and a line you decide to hold. SEE WHERE YOUR TIME GOES A clean, honest report of your screen time: total hours, pickups, notifications, and your most-used apps, broken down hour by hour. EARN YOUR SCREEN TIME Turn unlocking into a habit worth keeping. With Good App First, open something that matters before the apps that don't — and tie your screen time to real health goals. PRIVATE BY DESIGN Lookup is built entirely on Apple Screen Time. Your activity stays on your device. We never see, store, or upload your screen time — ever.

Features
Read full description

Most screen time apps are easy to dismiss. A tap. A passcode you set yourself. An exception you grant in three seconds. You already know this. You've tried them all. Sentence works differently. To unlock a blocked app, you write a sentence by hand — on paper — and scan it with your camera. Every time. No bypass. No exceptions. No "ignore for today." That moment of friction is the whole point. Most of the time, it's enough to make you put the phone down. HOW IT WORKS 1. Block any app or category — social media, streaming, games, news, anything. 2. Set your schedule — always on, a specific time window or a particular limit. 3. When you try to open a blocked app, you see a screen. Tap "Write Sentence." Sentence opens. 4. Write the sentence on paper. Hold it up. Scan it. The block lifts — for that session. 5. Tomorrow, you write it again. THE RITUAL Choose what you write each time you unlock: · Enquiry — why are you reaching for your phone right now? Answer honestly. · Affirmations — reinforce the person you're trying to become. · Literature — Seneca. Thoreau. Orwell. One line that reframes the moment. · Roasting — brutal honesty about what you're about to do with the next hour. · Custom — write your own sentence. Your commitment, your words. BLOCK ON YOUR TERMS · Block specific apps or entire categories · Time-based schedules — morning, night, all day, specific windows · Multiple block groups with different schedules and sentence types · Zen Mode — prevents deleting apps from your phone. Requires handwriting to disable. WHO SENTENCE IS FOR You've set screen time limits. You turned them off. You've tried grayscale mode. You adapted in a week. You've deleted the apps. You reinstalled them. You've tried willpower. It wasn't enough. Sentence isn't about willpower. It's about friction — a deliberate pause inserted between the impulse and the action. One sentence, written by hand, changes the calculus entirely. This is for people who are done with tricks that don't work. Access to Sentence features requires a paid subscription. Options include Monthly and Annual (with free trial). Manage or cancel anytime in your Apple ID settings. Terms of Use : https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict

The call

LookUp and Sentence both sit at 5.0 stars, but that hides the real split: 100% of LookUp's written reviews are positive against 60% of Sentence's. LookUp also leads on monetization model (free with in-app purchases vs subscription) and iOS requirement (16.6 vs 18.0). Sentence's advantage is ads (none vs shown) and ratings volume (10 vs 3). On price, rating, update cadence and in-app purchases there is nothing between them.
