Everyone's built a to-do list app at some point, right?

Well, there's a reason they’re so popular! Today, I’m excited to share 𝗙𝗼𝗰𝘂𝘀𝗙𝗹𝗼𝘄, a minimalist to-do app with a unique twist.

𝗪𝗵𝗮𝘁 𝗺𝗮𝗸𝗲𝘀 𝗶𝘁 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁: → Task batching by energy level: Organize tasks as high, medium, or low energy, instead of traditional categories.

→ Quick win filter: Highlight tasks that take less than 5 minutes. Integrated Pomodoro timer: Sync tasks with a timer to track your focus sessions.

→ “Tomorrow Self” feature: Leave context notes for your future self, making it easier to pick up where you left off.

→ Pomodoro Timer: Sync tasks with a customizable Pomodoro timer.

→ Offline support: Use the app without an internet connection, powered by an advanced service worker.

I built the v0 version in just under 4 hours! While it was mostly smooth sailing, I ran into some interesting challenges with hydration errors and service workers. Debugging these taught me a lot about building for performance and offline functionality.

My biggest takeaway? Start with the user’s problems rather than features. Asking myself, “What frustrates me about traditional to-do apps?”, helped shape the app into something fresh and practical.

You can try it out at Focusflow app I’ve also documented my process in the README.md on github.
