\DREAM SHEEP has been renamed to LambLock!/ 1,460 hours a year. That’s like working full-time for 9 months—on your phone. How much more of your life will go to scrolling? Ever say “just 5 minutes” on TikTok and end up losing an hour? Ever open X or Insta in the middle of work without even thinking? Ever stare at your phone before bed and then can’t sleep? LambLock is here to cut out that social media overkill, helping you rebuild your life on your own terms. (Research shows social media habits can wreck focus, sleep, mindfulness, and mental health.) We made this app because we’ve felt that struggle ourselves. ◆ What’s LambLock? An app blocker that stops you from doomscrolling—perfect before sleep or when you need laser focus.

Attacks doomscrolling at its core, cutting up to 50% off weekly screen time in beta tests. 3. Target only your problem apps—limit by time, day, or schedule.

Free start—anyone can hop in. ◆ User Raves: “My TikTok checks plunged from 30 times a day to 1!” “Weekly phone use down 50%—shocked!” “Way less SNS time—best digital wellness app!” “Free from social media stress!” ◆ Perfect For: - Anyone cutting screen time - Late-night scrollers with regrets - Focus, sleep, screen time, phone limit apps seekers - Distractibility/ADHD issues - Those wanting phone addiction help, self-control tools - Past social media/dopamine detoxers - Curious about dumb phones or minimalist launchers ◆ Try PRO Free Love it?
