Ask HN: Which calendar service for personal projects?

[ryqiem]

Hi HN!

I like to track which apps I've had open during my workday and output it to my calendar. This feeds my reflection on priorities, how often I context switch etc.

However, using the Google API for a personal project requires that I refresh the auth token every 7 days.

Do you know of any other services that have less restrictive requirements for personal API usage?

Thanks a lot!
