Holowork is for anyone who wants to manage their time well and stay present in the moment. Dig tunnels with Holdu while you focus. Every minute of concentration digs 1 meter deeper. Before you know it, you and Holdu will have built something together. Deep Focus mode blocks distracting apps during your session and lifts automatically when you're done. Track your daily focus time and depth to build a consistent habit. Every night at 10 PM, sit by the campfire with Holdu and take a break. Sometimes he reads you a poem while the fire crackles. As your tunnel deepens, so does your ability to focus.
