Tend helps you use those times well.
It is a simple service for the people you love most. It notices when too long has passed, schedules the call, plans the visit, and remembers the birthday before you have to. One honest check-in every Sunday, and nothing slips. Founding membership opens soon; the first five hundred keep their price forever.

Just your email. The arithmetic stays on this page.
1Estimates use U.S. Social Security Administration period life tables (2022), interpolated by age and sex, capped by your own remaining expectancy, multiplied by your stated cadence. For mothers and fathers, the years before you turned eighteen are counted at nearly daily density, in the spirit of Tim Urban's The Tail End. Real lives are not averages. Someone you love may far outlive every table, and none of us is promised the average. That uncertainty is not a flaw in the arithmetic. It is the argument for going this weekend. The full method.
