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/

Clarity is a Socratic thinking partner that helps you work through decisions, process emotions, and plan your next move — by asking the right questions, not giving you the answers. Unlike generic assistants that tell you what to do, Clarity uses Socratic questioning to draw out what you already know. Every conversation adapts to your values, goals, and communication style. Everything stays on your device. THINK THROUGH ANYTHING Whether you're weighing a career move, processing a tough conversation, or brainstorming your next project, Clarity meets you where you are. Choose from focused session types — brainstorming, processing, decision-making, planning, or open reflection. 8 THINKING FRAMEWORKS Go deeper with structured methods drawn from decision science and executive coaching. Apply Pre-Mortem to anticipate failure modes, Regret Minimization for direction-setting choices, 10-10-10 Analysis to weigh the long view, and Fear Setting when anxiety clouds judgment. Plus Pros & Cons, Friend's Advice, Values Alignment, and Ideal Week Design — each guided by hand-written prompts that ask the questions a wise friend would.

Verdict

The call

The clearest difference is monetization model: Clarity at freemium against Sentence's subscription. Sentence's advantage is ratings volume (10 vs 2). On price, rating, ads and in-app purchases there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Sentence sells 5 in-app purchases, starting at $1.99 per 7 days and Clarity sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 5.0 for Sentence against 5.0 for Clarity. That said, the two scores are not equally well evidenced: Sentence has 10 ratings behind it against 2, so its average is the more settled of the two.
