The best app blocker
for Android, at night

The best app blocker for Android depends on when you lose control. For nights, look for three things: a schedule that starts on its own, a block you can't dismiss with one tap, and a sensible way out for real emergencies. Android's own Digital Wellbeing covers the schedule but is easy to switch off. AppBlock, Freedom and Opal add stricter modes. one sec and ScreenZen slow you down rather than lock you out. Below is what each one does, so you can match it to your worst hour.

Start with what's already on your phone

Before you install anything, open Settings, Digital Wellbeing. According to Google's help page, you get three tools:

• Bedtime mode. Runs on a schedule, or while the phone charges within a time window. It can turn the screen grayscale, keep the always-on display dark and dim the wallpaper. It quiets the phone. It doesn't block apps.
• Focus mode. Pauses the apps you pick, so they can't open or send notifications, and it can run on a schedule. The catch for nights: "Take a break" unpauses them for a while.
• App timers. Close an app when its daily limit runs out. They reset at midnight, and deleting the timer reopens the app straight away.

For a lot of people, a scheduled Focus mode plus a phone charging across the room is enough. If you find yourself tapping "Take a break" at 1 a.m., read on.

Five Android blockers compared

AppBlock: the most flexible schedules

AppBlock runs on Android, iOS and as a browser extension. It blocks apps, websites, specific URLs and keywords, and has an allowlist mode that blocks everything except the apps you keep. Profiles such as Sleep can start by time, day, location or Wi-Fi network. Its Strict Mode makes blocks much harder to bypass, with options like a cooldown and approval from someone else. The site offers a free trial and a Premium plan but doesn't list prices.

Freedom: one block across all your devices

Freedom works on Android, iPhone, Mac, Windows, Chromebook and Linux, and a session started on one device can block on the others. Recurring schedules start sessions automatically, and Locked Mode stops you from quitting a session early. Its site lists Premium at $39.99 a year, or $199 once for lifetime access. Locked Mode is a Premium feature.

Opal: a full focus app with a hard mode

Opal is on Android, iPhone and Mac. It blocks on a schedule, sets daily limits and lets you choose how hard a block is to bypass, up to a level you can't cancel. On the US App Store its paid plans show at $19.99 a month and $99.99 a year. Check the Play Store for Android pricing.

one sec: a pause, not a wall

one sec runs on Android and iPhone. Before a chosen app opens, it makes you wait through a short exercise, like a breath, and the site cites a study with the Max Planck Institute claiming 57% fewer app openings on average. It can also block apps fully on a schedule. One app is free; on the US App Store, pro costs $6.99 a month, $19.99 a year or $99.99 once.

ScreenZen: free friction

ScreenZen adds a delay before a flagged app opens, and the delay can grow each time you come back. It also sets daily limits and can lock its own settings. It's free, with optional tips on the App Store. On Android it asks for Accessibility access to do its job.

Which one should you pick?

1. You scroll because it's easy. Try a pause first: one sec or ScreenZen. A few seconds of friction stops more mindless opens than you'd expect, and ScreenZen costs nothing.
2. You tap past anything soft. Pick a blocker with a real strict mode: AppBlock's Strict Mode, Freedom's Locked Mode or Opal's top difficulty.
3. Your laptop is the problem too. Freedom, because one session covers every device.
4. Your mornings are the problem. Most blockers stop on the clock. If the first hour after your alarm is where the day goes wrong, look for one that waits for your routine.

Whatever you choose, test it at 11 p.m., not 11 a.m. A block that feels strict in daylight can be one tap from off when you're tired. Our guide to blocking apps at night on iPhone and Android has the full setup, step by step.

Common questions

Is there a free app blocker for Android?

Yes. Digital Wellbeing's Focus mode is built in and free, and ScreenZen is free with optional tips. Most other blockers have a free tier with the strict features behind a paid plan.

Can Bedtime mode block apps?

No. Bedtime mode quiets the phone and can turn the screen grayscale, but apps still open. Use Focus mode or a dedicated blocker to stop them.

Why does my app timer stop working?

App timers reset at midnight, and deleting a timer reopens the app immediately. That's by design, which is why timers are easy to undo late at night.
