A focus app for people who need external structure

StrictBlock is not a medical treatment, but it can help create structure by blocking distracting apps and websites during focus sessions.

Download StrictBlock on the App Store

Why digital distractions are hard to resist

When distracting apps are always available, focus can break before you have time to make a deliberate choice.

Why external structure helps

External structure reduces the number of decisions you need to make in the moment. StrictBlock creates that structure by blocking chosen apps and websites while your session is active.

How StrictBlock creates boundaries

Use focus profiles, Pomodoro sessions, weekly reports, and session notes to make focused time more concrete and easier to repeat.

Best use cases

Focus profiles

Create saved blocking setups for studying, work, sleep, or deep work.

Pomodoro

Use focused intervals with app and website blocking built in.

Weekly report

Review focus patterns without turning the app into another distraction.

What people are saying

This app helps me a lot for my focus sessions”
Great app, it lets you start focus sessions and works a bit like Duolingo—you have to maintain your daily streak or it resets. For premium users, I'd love the option to schedule sessions to prevent procrastination.”

FAQ

Is StrictBlock an ADHD treatment?

No. StrictBlock is not a medical treatment or diagnosis tool. It is a practical iPhone blocker that can add external structure during focus sessions.

How can an app blocker help with ADHD-style focus?

It reduces in-the-moment decisions by making selected apps and websites unavailable while a session is running, so a short check is harder to start automatically.

What does external structure mean here?

It means the boundary lives in the session, not only in willpower: you choose what to block, start the session, and the distractions stay blocked until you end it.

Can I save different blocking setups for study vs work?

Yes. Focus profiles let you reuse a study setup, a work setup, or a wind-down setup instead of rebuilding the list each time.
