NFC and QR unlock

Unlock your apps by walking to another room.

Write your unlock key to an NFC tag or save it as a QR code. Leave it somewhere inconvenient, and the apps stay blocked until you go and scan it.

Any NFC sticker works

blokr writes your unlock key to a standard writable NFC tag or sticker. No special device needed.

Or just a QR code

No tag? blokr creates a QR code you can print, save or hand to someone you trust.

Distance does the work

Keep the key in the hallway, at the office or with a friend. The extra steps are often enough to break the habit.

Only your key works

blokr checks that the tag or code matches your own unlock key, so any other QR code will not open your apps.

How it works

  1. 1

    Create a block

    Pick the apps and when they should be blocked.

  2. 2

  3. 3

    Put the key somewhere else

    Write the tag or save the QR code, then leave it where reaching it takes effort.
