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/

Some apps you open on purpose. Some you open out of habit. Squirrel turns the habit into savings, money you keep and invest. I almost never chose to open Instagram, it was always a knee-jerk reaction to being on my phone with nothing better to do. Growing up, staying focused and managing my time has always been a real struggle for me, and as social media got bigger, I felt more and more susceptible to doom scrolling and being careless with how I used these apps. But I never wanted to delete them. I truly believe there's a time and place for all of them. A lot of my relationships are better because of social media, whether that be from sending memes to friends, looking back on old memories, meeting my college roommate (true story), and even meeting my now girlfriend (another true story). It would be hypocritical to say social media hasn't improved my life, it certainly has. But the problem is the other side of it, the hours I lost without consciously deciding to. I've tried the built-in screen time limits. I had Instagram capped at 40 minutes a day... that same week I spent 12 hours and 48 minutes on it, more than double my next most used app, because "ignore limit for today" is one tap away. The week after I started using Squirrel it was 1 hour and 45 minutes. The week after that, 56 minutes. That's just my usage, but the drop was hard to argue with. Squirrel is different because it doesn't treat these apps as the enemy. Other apps do the blocking part, but none of them connect it to the other thing people my age are behind on, which is investing. Two problems most college students and young adults have: too much time on their phones, and no idea where to start with money. Squirrel puts them together so each one fixes the other. HOW IT WORKS Pick the apps you want to put behind a decision. Opening one is your cue to set a few dollars aside for yourself. Nothing is charged. No money moves through Squirrel. It only records what you set aside. You invest it yourself, wherever you already invest, and tell Squirrel what you bought. The optional Portfolio upgrade tracks it so you can watch it grow. NOTHING IS CHARGED Opening a blocked app is always free. The amount you set aside is a note to yourself, like a swear jar. Squirrel never processes a payment for it, never connects to your bank or brokerage, and never moves money. You decide what to do with it, outside the app. There are no goals, no targets, no limits, and no streaks. There is nothing to fail. FREE AND PAID Blocking, setting money aside, and your savings history are free forever. The Portfolio view (holdings, growth charts, market prices, and projections) is an optional paid upgrade: $19.99 once, or $8.99/year auto-renewing. Prices may vary by region. Portfolio features shown in the screenshots are part of this upgrade, and have nothing to do with blocking or opening apps. No account, no login, no ads, no tracking. Everything stays on your phone and in your own iCloud. Squirrel is not a bank, broker, or financial advisor and does not give investment advice. You make every investment yourself. Any growth figures shown are illustrations, not guarantees.

Verdict
The clearest difference is monetization model: Squirrel at free with in-app purchases against Sentence's subscription. Sentence's advantage is ratings volume (8 vs 1) and iOS requirement (18.0 vs 26.0). 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
Both are free to download. Sentence sells 5 in-app purchases, starting at $1.99 per 7 days and Squirrel sells 2 in-app purchases, starting at $8.99 per year. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Sentence against 5.0 for Squirrel. That said, the two scores are not equally well evidenced: Sentence has 8 ratings behind it against 1, so its average is the more settled of the two.
