The relationship you have with yourself is the most important one you’ll ever build. When you promise yourself you’ll call your doctor, do the dishes, or hit the gym—you owe it to yourself to follow through. At your core, you are two people constantly interacting with one another: the one who decides, and the one who acts. That’s Du! — the dialogue between you and yourself. Introducing Du Contracts. This app lets you create simple “I Will” or “I Won’t” contracts with a 24-hour expiration. Within that window, you either complete or fail your contract. If you don’t update it in time, it automatically moves to your Failure Folder. Failures stay visible on your home page for at least seven days—a gentle but firm reminder of your unfinished commitments. Hold yourself accountable. Build trust with yourself. Start your first Du Contract today.
