Keep-In-Touch List: Who haven't I spoken to in too long?

Who you meant to ring, how long it's actually been, and who to do first. The friendships that lapse are almost never the ones you decided to let go, they're the ones where six weeks quietly became eight months.

WHAT YOU GET

- Set how often for each person; the list sorts itself by who's most overdue

- One tap to log that you spoke: that's the whole maintenance job

- Names the single person to contact first, with the number of days

- Dunbar's 5 / 15 / 50 / 150 layers as a guide to how often is realistic

- And an honest account of the 150, whose confidence interval nobody quotes

HOW IT WORKS

1. Add a few people: Start with the two or three you keep meaning to ring.

2. Say how often, and when you last did: “No idea” is a legitimate and revealing answer.

3. Do the top one: It's one message. It doesn't have to be interesting.

One file. Double-click it and it opens in the browser you already have: Chrome, Edge, Safari or Firefox. Nothing to install, no account, no subscription.

Nothing you type ever leaves your computer. There is no server involved, which is why it still works with the wi-fi switched off.

30-day refund, no questions asked.
