Productivity App idea Feedback Needed.📱🙋‍♀️

So I am thinking of making a “watssap for productivity” application where the app tracks productive time spent using a pomodo clock then make your productivity visible to your contacts. The app has the following features:

  • leaderboard
  • analetics
  • portfolio page
  • pomodoro clock

Do you think it would be useful to you or anyone you know?
What are the benefits or flaws?
