Project Overview

Deployed on Heroku - https://todolistsga.herokuapp.com/

Project Description

This is a ToDo app which lets you save your todo list one by one. You can add, edit and delete your list and you can also categorize them and there is a separate section for todolists with the status "done" for your convenience. There is a login and registration option, so each user has his/her own privacy. And whenever you are done with todo item, you can change the status and/or delete it permanently.
