The world's best, FREE screen time app that dramatically reduces your phone use. Optionally, upgrade to "Complete Habits" to earn screen time by completing habits you specify. Lusid helps you spend less time automatically checking your phone and scrolling, and more of it on focused work, meaningful goals, restful downtime, and the people around you. Instead of depending on willpower at the exact moment an app is calling your name, Lusid lets you create boundaries in advance and add exactly as much friction as you need to follow through. Whether you want one focused hour, a recurring daily boundary, or stronger protection from your most distracting apps, Lusid helps put you back in control of your time. Additionally, you can earn your screen time with "Complete Habits". Describe an activity, choose which apps or websites to block, and decide how much access you earn.

When you want access, Lusid can add intentional friction through a configurable waiting period, number challenges, or by scanning a QR code. You decide in advance how difficult it should be to override the boundary you created. "Complete Habits" supercharges Lusid by allowing you to block apps, perform a desired habit confirmed by AI camera verification, and unblock those selected apps as a reward.
