We built 4rem to solve a problem - to help us stop scrolling on our phones when we should be sleeping. The apps that are designed to keep us scrolling, liking and playing videos one after another are sometimes just too good at what they do, and cause us to sacrifice sleep. Screen time limits are too easy to override, and we need our phones nearby for what it’s useful for - keeping time, wake up alarms, and the occasional emergency call or text.

The 4rem Lock and app were designed to solve this problem by making your smartphone into a dumbphone which can only be unlocked by a physical device (that’s the lock). Automatically lock apps based on your routines or manually lock it anytime. Customize which apps to block and which to keep available.
