Although I'm pretty comfortable with my current Emacs-centric setup, I think it's useful to try out new tools to see if there is functionality I find useful. Over the last month I've been trying out a couple of different products:
Notion is a little hard to describe. It's a great way to take notes and organize ideas, but it can also be used to organize tasks into projects or store bookmarks.
If you've ever used a wiki, Notion works in a similar way but is much more user friendly. Definitely worth trying out, especially if you prefer taking and organizing notes in a visual way.
tomato.es is my usual go-to for pomodoro tracking, but for the last few weeks I've been trying FocusBooster. It has a desktop app which is handy, and it sends weekly emails with productivity stats. Unfortunately it does not have an API, but otherwise it's extremely polished and stays out of the way.
It also has a bunch of reports and stats which are always fun to look through.
Taskade is great for creating and organizing task-lists. I've used it for a couple of recurring checklists, but overall I prefer org-mode for anything more complex.
