FocusOS: App Blocker & Timer

Stop getting distracted every time you pick up your phone.

You open one app… then another…

and before you know it, your time is gone.

FocusOS helps you break that cycle and stay focused on what actually matters.

A simple focus app that actually works

FocusOS isn’t packed with complicated features.

It’s built to do one thing well:

help you focus by reducing distractions.

Whether you’re studying, working, or just trying to use your phone less, it gives you a clean and simple way to stay on track.

What you can do

• Block apps that pull your attention away

• Start a focus session instantly

• Track how much time you spend focusing

• Use a clean, minimal interface with no noise

Built for real life

If you’ve tried a productivity app or study timer before but didn’t stick with it,

this is different.

FocusOS is designed for people who:

Get distracted easily

Want to reduce phone usage

Need better focus during study or work

Locked Focus

Why it works

You don’t need more features.

You need fewer distractions.

Accessibility Service Usage

FocusOS uses Android's AccessibilityService API solely to detect which app is in the foreground and redirect you away from blocked apps during an active Locked Focus session.

The AccessibilityService is:

Only active when you have manually started a Locked Focus session

Used exclusively to detect and block access to apps you have chosen to block

Never used to collect, record, or transmit any personal data

Never used to interact with or modify other apps' content

You are always in control — you can end your focus session, disable the accessibility service, or uninstall the app at any time.

FocusOS helps you:

Stay focused longer

Build better habits

Take back control of your time
