This $9 key physically locks your most addictive apps

# This $9 Key Physically Locks Your Most Distracting Apps A new $9 device uses the same technology as contactless credit cards to add a physical barrier between you and your phone's most addictive apps—you have to physically scan the key with your phone to use them. It's designed to give you a moment of friction that might make you reconsider whether you really want to scroll through social media or check email for the hundredth time today. Think of it as a deadbolt for digital distraction.
