Break up with your smartphone at night. Loftie is the alarm clock that gets your phone out of the bedroom. The app sets up your Loftie Clock or Lamp, then gets out of the way: alarms, sounds, the sunrise light and wind-down routines, from your phone when you want them and from the clock when you don't. Loftie+ is the part of your day where the phone stays quiet: • Drift. Your phone senses your Loftie Clock nearby and puts your chosen apps to sleep the moment you walk into the bedroom. Walk out in the morning and they wake up with you. • Rest schedule. Block distracting apps automatically around your sleep and wake times, in three phases: Rest, Sleep and Rise. No willpower required. • The Loftie Card. A wallet-sized card that blocks your apps with one tap to your phone, wherever you are. Included with Loftie+. • Your rules. Choose exactly which apps and websites go quiet and which stay open, like calls, maps and music. • Beyond the phone. Block distractions on your laptop with the Loftie browser extension for Chrome, Firefox and Safari, and swap your home screen's app grid for a calmer Loftie widget. Free with your Loftie: • Alarms, sounds, the sunrise light and red mode on your clock, set from anywhere in the house • Hundreds of sounds, stories, meditations and breathwork for your clock's library • Wind-down routines for the clock and the lamp The app is free. Loftie+ is an optional subscription. Works with a Loftie Clock or Loftie Lamp; Drift needs a Loftie Clock.
