Surfing around the web I found this task manager on reddit that is called LunaTask. It claims on its homepage to have been developed with ADHD brains in mind.
In their homepage they show the following features:
Task prioritization with tools like Eisenhower Matrix, Pomodoro, WIP limit and Must/Should/Want.
Calendar and Time Blocking
Habit Tracker
Zoom and Google Calendar Integration
Journal
Mood, Energy and Stress Tracker
Encrypted notes
Email integration
Browser integration
Zapier
They offer a lifetime purchase for $180 and a monthly sub of $6 or $5 depending if you go with the anual option.
I’m going to be testing it out this month and see how it goes.
