Friendship is a scheduling problem
Stop saying “we should catch up.” Put it on the calendar once.
Research on adult friendship keeps landing on the same finding: what keeps friends close isn’t grand gestures, it’s frequency of contact. The intent is always there — the moment never is, because deciding when is a small negotiation both of you keep postponing.
CatchUpCal removes the negotiation. You and a friend agree a slot once — a short, 30-minute call, weekly or monthly, timezone-aware — and it lands on both your Google Calendars forever. Call on whatever you already use. Mark it done. Watch your streak grow.
About 15 friends on a rotation works out to one short call every couple of days — enough frequency to stay close, spread out so it never drains you.
