Screen time apps aren’t effective for many people because they ultimately rely on your own willpower. You can remind yourself to stop scrolling or set a timer, but these notifications are easy to ignore.
Autonomous Key takes a different approach to this problem in that it is simply a physical device. This is an NFC key that can be paired with a companion app to lock out distracting apps. So instead of tapping a button to bypass the block, you have to physically scan the key with your phone to regain access to locked apps. Each unlock session can last up to 60 minutes before the app automatically locks again.
This physical requirement makes the idea compelling. By leaving your NFC key in another room, or even your office or gym, instead of relying on self-control, you can turn the unconscious urge to open Instagram or TikTok into a conscious decision that requires extra effort.
At just $9, Autonomous Key is significantly cheaper than competing products like Blok ($29), Unpluq ($26.50), and Brick ($59).
Brick offers some more advanced features, such as sleep mode and the ability to block in-app purchases, while Autonomous Key covers the core functionality at a fraction of the price.
The key itself is compact at about 3 inches long and works with smartphones running Android 8.0 and above and iPhones running iOS 15 and above.
This companion app also provides AI-powered insights, tracking how often you unlock distracting apps, how long they remain accessible, and when you’re most likely to access them.
In particular, the AI sums up your habits with an intentionally cheeky personality. For example, if you lock an app and then repeatedly unlock it, it may decide that your key was clearly not far enough away and suggest you put it in an inconvenient location.
Additionally, unlike many app blockers, there are no subscriptions or premium tiers required to unlock additional features. One key can be paired with multiple phones, making it a practical option for people and families with multiple devices.
However, during testing, we noticed that NFC scanning may require multiple attempts to register. As such, it’s probably not the best choice for locking down important apps (like messaging or email) that you need to access throughout the day.
There’s also the question of what happens if you lose your key. The current workaround if the app is locked is to uninstall and reinstall the companion app. If it’s already unlocked, you can simply remove the key from your account. The company says it is developing a method to unlock backups that will come in a future update.
Autonomous Key is currently in beta following a Kickstarter campaign and began shipping earlier this month. Available in 5 colors: pink, orange, blue, gray, and brown.
