Off It

We live in the most precisely engineered distraction environment in human history. YouTube, Instagram, TikTok - algorithms built by some of the world's best engineers are designed to keep your eyes on the screen. For teenagers whose self-regulation is still developing, "I should stop" is a thought that rarely becomes action. Off It was built to face that reality head-on. [Why Off It is different] We don't block anything. Off It doesn't lock apps or force restrictions. Instead, it turns the time you spend on your screen into a visible number with real consequences. In Parent & Child mode, the child's allowance decreases as their Discipline Score drops. Kids respond to a shrinking allowance far more viscerally than to abstract advice like "you should study." The choice stays theirs. Off It just makes the consequences visible. [Key Features] Automatic screen-off tracking Accumulates the time your screen stays off, 24 hours a day. At the end of the day, you see exactly how much distance you put between yourself and your phone. Discipline Score A daily score from 0-100. Using immersive apps - games, social media, video - chips away at your score in real time. Allowance integration (Parent & Child mode) Parents set a base allowance. The child's actual payout adjusts automatically based on their Discipline Score. No more "put the phone down" - the number says it all. Immersive content auto-detection Automatically identifies apps by category: games, social media, streaming, music. You choose which categories to monitor. Nudge messages Parents or accountability partners can send words of encouragement - support, not control. Regional ranking Compare screen-off time with nearby users and maintain healthy competitive motivation. [Who it's for] - Teens and adults who worry about their own phone use - Parents looking for something beyond "just put it down" - Anyone who wants to start with one small habit - People who want to reclaim agency from Big Tech design [Privacy] - Your data is never sold or shared for advertising purposes. - The installed app list is used only for on-device category detection and is never sent to our servers. - Deleting your account immediately removes all your data. Off It is not a replacement for willpower. It's a supplement that helps you make your own choice.
