ScreenZen vs Quizlock: a free pause, or a pause that teaches you

ScreenZen is one of the most liked screen time apps around, and it's easy to see why. It's free. There's no subscription. It's paid for by donations from people who want it to keep going. And it works for a lot of them: the site says over 500,000 people use it every month.

We make Quizlock, so we're not neutral. But this isn't a page about why ScreenZen is bad, because it isn't. It's about two ways of solving the same problem, and which one fits you.

What ScreenZen does

You choose the apps and websites you want to cut back on. When you open one, ScreenZen puts a pause in the way. You wait a few seconds and see a prompt, which you can write yourself, like "what are you looking for?". Then you decide whether to carry on. On top of that you can set daily limits, schedule blocks for focus time, and limit how many unlocks you get each day.

Its FAQ says there's a lock mode that protects against common loopholes, including uninstalling the app. ScreenZen runs on iOS, macOS, Windows and Android, and it now sells a companion device called halo that you put in your bedroom or on your desk.

The short version

Why a pause works, and when it stops

A pause works because most app opens aren't decisions. Your thumb gets there before you've thought about it. A few seconds of waiting gives your brain a chance to catch up and ask if you meant to do this. One ScreenZen reviewer on its site says the pause "annoyed me just enough" that they stopped opening apps unless they were taking a real break. That's the whole idea working.

The weak spot is that waiting doesn't need your attention. You can sit through a pause while still half asleep. After a few weeks, plenty of people stop reading the prompt and just wait for the button. The pause turns into part of the loading screen.

ScreenZen

1. Open Instagram
2. Pause and a prompt appear
3. Wait it out
4. Tap continue and scroll

Great at first. Easy to wait through on autopilot later.

Quizlock

1. Open Instagram
2. Quizlock asks one question
3. Think, answer, earn 2 minutes
4. Scroll, one fact richer

You can't answer on autopilot, and the pause pays you back.

A ScreenZen user asked for this

One of the reviews on ScreenZen's own homepage asks for something very close to Quizlock. The reviewer says they'd love "a quiz pause alternative where you can maybe upload a text or csv file with notes and flashcard information". They're learning Korean and want to "review 10 vocab words correctly before unlocking the app".

That's a fair summary of the difference between the two apps. ScreenZen asks you to stop and think. Quizlock asks you to stop and think about something specific, something you wanted to learn anyway.

How Quizlock works

Quizlock locks the apps you choose through Apple's Screen Time system. When you open one, you get a quiz question on a topic you picked. Answer right and you earn 2 minutes. Your minutes collect in a wallet that holds up to 30, so a short run of right answers buys a proper break. When the minutes run out, the apps lock again.

Topics can be anything you type: Korean, the periodic table, art history. You can also make quizzes from your own material. Upload a PDF, take a photo of your notes or paste a web link, and the questions come from that. So the Korean learner above could put their vocab in front of TikTok.

It isn't unbreakable. It runs on Screen Time, like every iPhone blocker. But the gate gives you something, so there's less reason to look for a way around it.

Price: free vs paid

ScreenZen wins on price, plainly. It's free, and you can donate if you want to support it. Quizlock is $69.99 a year or $12.99 a month after a 7-day free trial. What the money pays for is the learning: the questions, the topics you type in, and the quizzes made from your own files.

Which one to try first

If you've never used a screen time app, start with ScreenZen. It costs nothing, and a week with it tells you a lot about your habits: which apps you open most, and whether a few seconds of waiting is enough to change your mind.

1. 1
   Week one: try the pause

   Install ScreenZen, add your two worst apps, and write a prompt that makes you think, like "what are you looking for?".

2. 2
   Check how you respond

   If you close the app after the pause most of the time, you've found your tool. Keep it.

3. 3
   If you wait through it

   That's the sign a pause has stopped working for you. Try Quizlock's 7-day free trial on the same two apps and see whether a question holds where a timer didn't.

Either way, don't lock everything. Two or three apps where the hours go is enough, and it keeps maps, messages and work apps out of the way.

Where ScreenZen is the better pick

• You don't want to pay anything. ScreenZen is free.
• You need it on Android, Mac or Windows. Quizlock is iPhone only.
• You want detailed limits, schedules and open counts more than you want to learn something.
• A pause already works for you. If it does, keep it.
