Simple tracking for how long it’s been since you did something.
List activities in Activities, and click “Today” to mark that you completed the task today. The $\Sigma$ Since property will show you how long it’s been since you completed the task.
Copy Activities wherever you would find it useful. Either from the ⠿ menu, or with /linked “Linked view of a database.”


To customize the date of an activity, you can click “↗️ Open” after pressing the Today button, which will navigate you to the entry in Event Log where you can customize the date.


The second database is the Event Log. You likely won’t look at this table directly. Each row is an entry in Activities, and a Date for when the activity took place.
Add tags to your activities and create views filtered on the activities you care about.

Create an additional property to track when it’s been a little too long since you did something. Maybe you want to meal prep every 7 days, maybe you want to change air filters every 60.
Some habits can be tracked on longer timescales. Adjust the $\Sigma$ Since formula (or create an additional property) to operate on “Weeks” or “Months” instead of days.
