¦What I want to do

I'm trying to implement an app that enables to manage my current tasks and their due dates on the screen like Gantt chart. Also I hope I can track each task status and see due dates at a glance.

Regarding its logic, I want the app to do the below actions.

·Adding a new task

·Updating descrioption of a task, such as Due date

·Deleting the task when I'm done.

..etc

¦What I want to ask

I imagine making a task management app with UI like the below image.

I wish I could take advantages of something for reference.

Have you ever made this kind of app?

I'd appreciate it if you could give me some advice and any clues.

Best,
