Building a unified daily planner in high school: Looking for UX & layout feedback!

Hi everyone! I'm Winn Htut Hein, a high schooler from Myanmar. Following up on my last project, I wanted to share my other live app, BLOC.

BLOC is a minimalist daily planner that unifies tasks, focus blocks, habit tracking, and a calendar view all into a single dashboard. My goal was to create a clean workspace without the clutter of traditional apps.

Since I am learning how to properly architect frontends and manage complex UI states (syncing habits, timers, and calendar events seamlessly), I would love to get your honest feedback.

• How is the layout/UX? Does it feel intuitive?
• If you look at the repo, how can I clean up my frontend state management?

I'm eager to learn how to make my code and interfaces cleaner. Any advice or criticism is incredibly helpful!
