AppBlock vs BlockSite: Which Blocker Fits Your Phone and Browser? (2026)

AppBlock and BlockSite sound interchangeable, and both will stop you from opening things you shouldn't. But they start from different problems.

AppBlock is built around your phone. Its strength is rules: when apps lock, where they lock, and how hard it is to undo.

BlockSite is built around websites. Its strength is what it can block in a browser, including whole categories and keywords.

So the better choice depends less on which is "best" and more on where you actually lose your time.

AppBlock vs BlockSite at a Glance

Features come from each company's App Store listing and website. Plans change, so check inside the app before you pay.

Where AppBlock Is Stronger

Rules that fit your day. AppBlock's listing says schedules can run on time, location, or Wi-Fi. That means you can block social apps whenever you're at the office without setting anything up each morning.

Strict Mode. This is the main reason to choose it. Strict Mode prevents you from changing your blocks while they're active. One long-term user in r/digitalminimalism sets a timer for about five days to lock out social apps, and calls AppBlock "kinda the only effective app I've been able to find."

Limits on opens, not just minutes. App Open Limits suit the habit of checking an app again and again for just a few seconds.

In-app blocking on Android. From version 7.5.0, AppBlock can block Instagram Reels, YouTube Shorts, and similar sections without blocking the whole app. See how to block Reels and Shorts but keep your messages.

AppBlock's weak spots

The free tier is tight on iPhone. You get up to 2 schedules, 30 minutes of usage limits a day, and Strict Mode for up to 12 hours.

It isn't unbreakable. A commenter on that same thread said "It's too easy to undo" and pairs AppBlock with a physical blocker. Another user there found Strict Mode almost impossible to bypass, so your results depend on your setup and how determined you are. On iPhone, AppBlock uses Apple's Screen Time framework, which has the same loophole as other blockers.

Where BlockSite Is Stronger

Websites and browsers. BlockSite's App Store listing says it works with Safari, Chrome, and Firefox. If your problem is news sites, shopping, or Reddit on a laptop, that's the core of what it does.

Blocking by category. With Premium, you can block groups like Social Media, Shopping, or Entertainment with one tap instead of listing sites one by one.

Blocking by keyword. Also Premium. This helps when distractions are spread across many sites.

Focus Mode and sync. BlockSite's site lists Focus Mode for timed sessions, plus sync so that the same sites and apps are blocked on your devices.

Redirects. You can send yourself to a useful page, or a custom block page with a reminder, instead of a dead end.

BlockSite's weak spots

Its protection is a password, not a lock. Password Protection is a Premium feature, and it's only as strong as your memory of the password. Having someone else set it helps.

Some users find it easy to switch off. A paying user in r/nosurf wrote in 2023: "I can turn it off easily." They also couldn't log in to the same account on their phone, which matters if sync is why you're buying. That's one older report, so test sync during the trial.

Check privacy for yourself. Older Reddit threads from 2019 and 2020 asked whether BlockSite was safe, and we didn't find a clear answer in them. Read the current privacy label in the App Store or the Chrome Web Store listing before installing, as you should with any tool that sees your browsing.

Free Tier Compared

AppBlock publishes its limits:

BlockSite says you can block websites and apps for free. Its listing puts keyword blocking, unlimited category blocking, and password protection in Premium, so the free version is closer to a basic block list.

Pricing

The App Store shows several price tiers for each app, and the price you see may depend on your plan or offer.

BlockSite's pricing page also mentions a 30-day guarantee. Be careful with comparison posts written by either company. BlockSite's own article, for example, describes AppBlock as mostly Android-focused, while AppBlock publishes separate iPhone features and pricing.

How to Choose

Track where your lost time actually goes for one day, using Screen Time or Digital Wellbeing, then:

• Mostly phone apps? Go with AppBlock. Set one schedule and turn on Strict Mode.
• Mostly websites on a computer? Go with BlockSite, or a browser-only blocker if you don't need phone coverage.
• Both? Start with the device where you lose the most time. Paying for two tools only makes sense if one isn't covering the other.
• Do you bypass everything? Neither app will solve that alone. Look at physical blockers or a timed lock box.

The Digital Feng Shui Angle

In Feng Shui, you deal with a draft by finding where the air gets in. Sealing every window in the house is rarely the answer.

Choosing between these two tools works the same way. Before you compare features, find your draft. If it's the phone in your hand on the couch, a website blocker won't help. If it's a browser tab during work, a phone schedule won't either. The right tool is the one standing at the door your attention actually leaves through.
