We stripped away the clutter so you can do one thing the moment you open the app: Act Now. 【Why Just Start?】 1. A Companion from the Stars: Laika Remember Laika, the first dog in space? She didn't disappear; she traveled to your phone. When you focus, Laika waits by your side on the screen. Whether you're studying late or working early, she is there. It’s not just a timer; it’s a warm, silent guardianship. 2. Pro Features Unlocked (Yes, Free) We believe your growth data belongs to you. No paywalls for self-reflection. 3. Unlimited Categories: Coding, Reading, Meditation—create as many tags as you need. Free. 4. Full History Stats: Your every minute counts.

When you start the timer, you will see the glimmering starlight left by others who have traveled this path before you. Just like looking at the night sky, these lights are echoes of past efforts from people around the world. It’s a subtle "cloud companionship" that tells you: someone else has worked hard right here, just like you.

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.
