Love this idea. For me it's more about personal capacity management -- just starting up here I am hesitant to set a cadence for too many contacts because I'm going to have 100 people that I'm overdue on (some of which I have contacted but haven't recorded history, others I haven't yet). Not critical but could make for a friendly onboarding experience for users. I think Contactually did something like this originally (i.e., it would limit how many keep-in-touch nudges it would provide and it would be random from the set of "overdue" contacts

This would be helpful. If I may expand on the idea, here's what I was thinking:

The one things that's making me crazy right now is the linear keep-in-touch intervals. What I'm finding is that it doesn't make sense for me to keep in touch with people every week or every two weeks or every three months.

I'd really like to see more of a spaced repetition approach. In fact, I've wondered if there are any psychological studies on length of time between contacts for keeping a relationship "warm."

"Contact Warm Up" Variable Reminder

For example, let's say I meet a new person and get their business card, and I want to stay in touch. How about an interval for staying on that person's radar, a "Contact Warm Up" as it were:

"Long Time Friend/Family" Variable Reminder

On the other hand, for longtime friends, it might be more of an "Orbit." As a thought: the Earth moves around the sun about every 365 days, yet it's not always equidistant to the sun, but an elliptical orbit. I'd like to do that with people are fixtures in my life. Maybe that looks like:

--> The benefit of the "Orbit" track is that it helps me space out all the people with whom I'd like to stay in touch. It also makes it so that I don't have 20 people every day that I need to connect with.

Whereas, for people I naturally have contact with on a frequent basis, they're on a "Special Occasions Only" track, which I can set up with Custom Reminders.

Something like this, I think, is how relationship really work, unless one's entire Dex is made up of potential clients--hey! That might be a great edition--the "Sales Track."
