Todo

Free and open-source Minimalist Weekly Planner Focused on Privacy.

Simple, efficient, versatile - just great! After trying out dozens of to-do and note-taking apps, this one serves me as an ultimate solution :)

Org-mode is more than just a tool. It’s a way of life, a philosophy. It helps you organize your thoughts and tasks in plain text. You can write notes with collapsible headings and lists, code, author documents and more. You can export your work to different formats or publish it online with a single command....

Todoist is a task management app and online to-do list available over 13 platforms, including iOS, Windows, Chrome, and more.

Clean and Minimal Open source Slick and fast

Just what I was looking for days : list by category with priority and even more ! Thanks a lot !
