Focus D
Read full descriptionHide full description
A Pomodoro timer that rewards you for building focus. You know the feeling. You picked up your phone to do one thing, and 20 minutes vanished. Focus isn't a personality trait — it's a skill. Skills are trainable. Focus D combines three things into one loop: • Timer — Time-box your work. Start small, build momentum. • Tasks — Break it down. One thing at a time. No cognitive overload. • Rewards — Satisfy yourself. Earn tomatoes, redeem them for wishlist items you set yourself. This isn't just another timer. It's built on BJ Fogg's Behavior Model: Motivation + Ability + Prompt. Most Pomodoro apps give you a timer and a notification — that covers Ability and Prompt, but they leave Motivation entirely to you. Now, Focus D closes the loop. What makes Focus D different: • A complete focus training system, not just a countdown • Wishlist rewards create incentive — earn what you care about • Task management built in — no app switching • Deep analytics in three sections — Daily snapshot, Trends over time, Insights that discover your patterns • Clean, native design. No account required. Your data stays on your device. • Live Activity & Dynamic Island support From the developer: I led an employee incentive management project before building Focus D. I saw firsthand how motivation systems change behavior — when you align ability, motivation, and the right nudge, people transform. I applied that same thinking here. This is the app I needed when I was the one scrolling. Focus D is the first app from DA3H. More tools are coming. Built for people who want to spend their time better.
