There is no universal number, but there is a useful one. How to pick a cadence per friend instead of feeling vaguely guilty about all of them at once.

The right interval is the longest one at which the friendship still feels current. Past that, every reunion starts with catching up instead of just continuing.
A daily-text best friend and a once-a-year university group are both healthy. The mistake is applying one cadence to everyone, then feeling like a bad friend toward the people who simply sit at a slower tempo. Closeness is not the same as frequency. Some of the strongest bonds run on three real conversations a year.
A better question than "how often" is "at what interval does this friendship still feel current?" For one person that is a fortnight. For another it is a season. Name the interval per friend, and the guilt stops being a single vague cloud and becomes a handful of small, answerable questions.
A rough split that works for most people: an inner circle you want to hear from every week or two, a middle ring of monthly-to-quarterly people, and an outer ring you genuinely like but realistically reach once or twice a year. Putting a name in a ring is not a demotion. It is permission to stop measuring a yearly friend against a weekly standard. (The 5-2-1 rule gives these rings a memorable name and a weekly budget.)
The reason cadence fails is not that you stopped caring. It is that an interval longer than a few weeks is invisible to working memory. You cannot feel that it has been eleven weeks since you spoke to someone you love — a problem explored in depth in why adult friendships fade after 30. That is exactly the gap Friendship Tracker fills: you set a reach-out interval per person, and the list quietly tells you who is overdue instead of asking you to hold thirty separate clocks in your head.
