Using task planner apps (e.g. Todoist, Notion, OneNote etc) to keep track of girls in your rotation?

Anyone tried using apps such as the ones in the title (or others) to keep track of girls you are dating? Might seem rather silly/excessive/socially uncalibrated to do this.... but I can see it being useful for remembering dates/details and not get confused between different girls (e.g. mixing up birthdays, or the name of their dog etc)

I started using Notion and realised it has potential for this purpose. You can use the calendars, tables, gallery and subpage functions to keep track of each girl, upcoming plans, important details that they would get angry about if you forgot etc.

Everyone who uses apps, what do you use?
