Deep work, together

Lock In Hour

Lock In Hour is a web app plus a Chrome extension where people lock in together for scheduled deep-work sessions called Dives. Write your Dive plan and join the next Dive on the hour: the extension blocks distractions, Sonar checks for your phone on your own laptop, and a floating window keeps the Dive in view. Every Dive earns a Deep Score and Fathoms, which roll up into the Depth Chart, a global daily leaderboard of X handles. Nothing from your camera ever leaves your laptop.
