I want to make an app in which users can
1. choose a project they wish to complete, set up daily goals
2. share their plans on the app, add tag.
3. Other user can search certain tag to see any posts under this tag. Choose their ideal study buddy, private chat them.(also include function such as voice call, send picture. )
4. Add a virtual coin system, in which they get coins for task complete
5. users trade in virtual coins and unlock puzzles pieces(This is just cute pictures)
