What an iPhone app blocker does

An iPhone app blocker helps remove access to distracting apps when you want to study, work, sleep, or stay present.

People use an app blocker for the same reason they want a dumb phone: less scrolling, and a real boundary around the apps that pull them away.

Why people need app blocking

Many distractions are automatic. You can open the same app before you notice what happened. StrictBlock creates friction by blocking selected apps during focus sessions.

App blocking plus website blocking

StrictBlock helps you block distracting apps and websites together, which matters when procrastination moves from apps to Safari or another browser.

Focus profiles and Pomodoro sessions

Create saved blocking setups for studying, work, sleep, or deep work, then run timer or Pomodoro-style sessions with the right distractions blocked.

Best use cases

App blocking

Block the apps that pull you away during a focus session.

Website blocking

Block distracting sites alongside app distractions.

Focus sessions

Use timers, Pomodoro, and saved profiles for different routines.

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

What does an iPhone app blocker actually do?

It removes access to the apps you select while a focus session is running, so opening a distraction takes a deliberate choice instead of a reflex.

Can StrictBlock block apps and websites together?

Yes. You can block distracting apps and websites in the same session, which helps when the same habit moves from an app to Safari.

Do I need Screen Time permissions for StrictBlock to work?

Yes. StrictBlock uses Apple's Screen Time permissions to enforce the apps and sites you selected. Check those permissions if blocking does not start as expected.

Is StrictBlock just another focus timer?

No. A timer tracks time. StrictBlock combines a timer or Pomodoro session with app and website blocking plus streaks, reports, and session notes.
