Tangentially related, but after years of trying out (and struggling with) hundreds of calendar and schedule apps, in the end what was best for me turned out to be a simple text file that I keep updating and look at each day. A line on it represents a day and begins with (dd/mm), and events for the day are plaintext separated by commas. Each day gone by gets erased. Absolutely zero friction and I can see an entire month of stuff at a glance so I'm always aware of what to do. Can't believe it took me so long to go back to such bare basics, and now I strive to reach this level of brutal basic frictionless simplicity in my own toy projects.
