Choose which city you come out of, and decide what your devices can reach. PICK A CITY Come out in Tampa, Detroit, New Jersey, Las Vegas, Helsinki or Jeddah. Switch whenever you like, as often as you like. Adding a city takes one tap. BLOCK WHAT YOU CHOOSE Turn off ads and trackers, adult sites, malware and scams, gambling, or social media. Add any site by name. Changes take effect straight away, with nothing to reinstall. FOCUS: MAKE IT STICK For staying away from porn, gambling or endless scrolling. Tightening is instant; loosening waits 24 hours and can be cancelled, so a weak moment can't undo your decision. With a day count, a small social media allowance you open when you choose, and an "I need a moment" button for when an urge hits. BUILT FOR A HOUSEHOLD Give one phone different rules from another. Turn on safe search so results stay clean. Set quiet hours for school nights, and pause everything when someone needs a break. SEE THAT IT IS WORKING Each device shows whether it is connected and how much has been blocked. You see the count, not a list of what anyone visited. YOUR KEY IS MADE ON YOUR DEVICE The key that identifies this phone is created here and never sent to us, so we could not hand it to anyone else. ONE ACCOUNT, EVERY DEVICE Sign in with a passkey and Face ID, or a link in your email. No password to remember. The same account works on the web.
