The Dunbar App
For slow, steady friendships
Free · Designed for iPhone. Not verified for macOS.
Dunbar helps you keep the people who matter close — without turning friendship into another feed to manage.
Built on Robin Dunbar's research that we can only hold about 150 stable relationships, the app sorts everyone you know into four circles, each with its own natural rhythm:
Inner (5 people) — weekly
Close (15 people) — monthly
Friends (50 people) — quarterly
Network (150 people) — yearly
Every call, text, and get-together you log becomes a touchpoint. Dunbar's rhythm engine quietly compares how long it's been since you last connected with someone against their circle's rhythm, then surfaces a short, honest list of who's actually due for a reach-out today — not a guilt-driven streak or a notification flood, just a few gentle nudges.
What it does:
• Sorts your contacts into four rhythm-based circles
• Tracks touchpoints from quick logs, plus optional Contacts and Calendar import
• Surfaces a small, prioritized "reach out today" list each day
• Shows drift at a glance, so no one quietly falls out of touch
• Visualizes your whole social world as concentric circles
Privacy, by design:
Dunbar is local-first. Your contacts, calendar events, and touchpoints are stored on your device and never uploaded anywhere. There's no account required to use the app, no ad tracking, and no social graph shared with anyone.
Dunbar isn't a CRM and isn't social media. It's a quiet, personal tool for making sure the people you care about most don't slip through the cracks of a busy life.
