Need feedback on Pomodoro Clock made with React Hooks

Link -
Github Repo -

I started making this with Class components and then I made it unnecessarily complicated, so after some time I discarded that and started making it from scratch with React Hooks.

I think the design is not that great and I could have done better (Let me know of any design improvements/changes that I could do), but I think the code is much cleaner than what I wrote before.

Appreciate any feedback. :slight_smile:
