Meet the App

Blok and Unblok
Instantly start or stop a focus session by scanning your Blok. No fiddling with settings or distractions—just tap and lock in.
Customize Apps / Websites
Easily block distracting apps and websites by category—like Social, Games, or Entertainment—or pick them one by one.
Schedule Bloks
Set Blok to turn on automatically during key times—like work hours or bedtime. Stay consistent without even thinking about it.
Analytics
Stay motivated with a streak counter and daily history. See how long you've stayed focused and track your progress over time.
Remote Bloks
Activate or deactivate Blok even when you’re not near it. Great for sudden focus needs or managing Blok from a distance.
Strict Mode
Lock it in for real. Turn on Strict Mode to prevent the app from being deleted during a session—no uninstalling your way out.
Emergency Bloks
Get 3 free Emergency Unbloks when you first download the app for moments you truly need access. After that, extras are $4.99 each.
Break Bloks
Need a breather? Tap to take a short break—1, 5, or 15 minutes. Blok automatically resumes your session when the break ends, so you stay in control without losing momentum.

Any last questions?

How is Blok different from built-in screen time management tools?

Unlike software-based solutions that can be easily bypassed, Blok introduces a physical barrier to accessing distracting apps. This tangible aspect reinforces discipline and makes it more challenging to revert to time-wasting applications, thereby enhancing its effectiveness. ​

What happens if I lose my Blok?

It's not the end of the world. We gift you 3 freebie Emergency Unbloks when you 1st download the app, then it's $4.99 per extra one.

Is there an app that accompanies Blok?

Yes, Blok is complemented by an app available on the App Store and Play Store. The app allows you enter and exit blok sessions, customize which applications to block, and track your previous blok sessions. ​

Does Blok work with both iOS and Android devices?

Yes. Search up "Blok" on the App Store or Play Store.

Can I use one Blok with multiple devices?

Yes

What is your return policy?

We offer a 30-day money-back guarantee. If you're not satisfied with Blok, you can return it within 30 days of receiving it, provided it's in its original condition. ​

Three weeks in and my screen time dropped from 6 hours to under 2. Didn't think it would work this fast. The tap-to-start thing feels like flipping a real switch.

Blok lives on my desk now. Tap it when I sit down to code, tap it when I'm done. Clean habit. Nothing else I've tried actually stuck.

Finally finishing books again. Used to buy them and never open. Something about the physical tap that stuck where apps alone never did.

First thing that's made a real dent in my Instagram habit. Every other app-blocker I could talk my way out of in 10 seconds.

My kids noticed before I did. My 6-year-old asked why I wasn't on my phone at dinner anymore. Worth every penny just for that.

ADHD brain loves this. The friction of reaching for the card is enough to break the doomscroll loop before it even starts.

Might as well be the only app blocker

Also I’ve noticed a change after Blok in my relationship with my phone. Decreased my screen time but also even when I’m actively bloking, I find myself using my phone for things I’d like to do more: connecting with friends or reading long form..

I got really flustered about something at work today and would normally gravitate towards scrolling on my phone as a mental break but since all my favorite apps were bloked i had a productive meeting with a coworker instead haha..
