Obsidian is a highly customizable knowledge management app that empowers users to build personal note networks with markdown, backlinks and visual graph views. Unfortunately Obsidian is very hard to use and requires a a lot of time to set up and maintain.
Routine not only goes further than Obsidian by providing a more powerful personal knowledge management (PKM) experience through custom types, views and canvases, Routine synchronizes data from all the other services you use on a daily basis, centralizing all your information into a single workspace. Finally, Routine supports collaboration, allowing teams to work together and power their workflows.
