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.

Most habit trackers only show you the good side. Habitug doesn't. Track the habits you want to build and the ones you want to break — with a score that goes up for good habits and down for bad ones. Finally, a habit tracker that tells the whole truth. Streaks and accountability Streaks are at the heart of Habitug. Every day you complete a habit, your streak grows. Every day you give in to a bad habit, your counter resets. Whether you're building a morning routine, working toward daily goals, or trying to break bad habits for good — your streaks keep you honest. Calendar heatmap See your behavior over time with a visual heatmap calendar. Green days, red days, patterns you didn't know you had. Your history becomes your most powerful motivation tool. Positive and negative habit tracking Track days without bad habits the same way you track streaks for good ones. Screen time, junk food, any habit you want to eliminate — Habitug measures what others ignore. Particularly effective for people with adhd who benefit from immediate visual feedback and clear consequences.
