FAQs

What is FocusOS?

FocusOS, also written Focus OS, is a free productivity app with no sign-up. It locks your Windows computer and Android phone to one focus session. More about FocusOS.

Is there a free productivity app with no sign-up?

Yes. FocusOS is free and needs no sign-up, account or email. How to choose one.

Can one app lock my computer and phone together?

FocusOS can. Start a session on your Windows computer, press Get a key, and type the key into the Android app. Your phone locks for the same session, and calls still work. Using it to study.

Do I need an account?

No. There’s no account, sign-in or email address. Download it and start a session.

Does FocusOS store my data?

Your sessions, plans and notes are saved on your own device, where you can read or delete them. They’re never sent to us. Nothing goes online unless you press a button that says so. If you ask for a phone key, the key and the time left are stored in the cloud so your phone can follow the session, then deleted. That holds nothing about who you are.

Is it really free?

Yes. There are no paid features, ads or subscription.

Does the webcam record me?

No. During a session, pictures are checked for a held phone and whether you’re at the desk, then thrown away. Nothing is saved or sent, and you can turn the webcam off.

Can it lock my phone too?

Yes, on Android 8 or newer. Press Get a key on your computer and type the key into the FocusOS Android app and the phone locks until the session ends. Calls and emergency calls keep working. iPhones aren’t supported.

Which computers does it run on?

Windows 10 and 11.
