WhoKin: Relationship Tracker

Track your relationships. Know who needs you — before they drift away.

No sign-up needed. Open the app and start in seconds.

Most people don't lose close friends to drama. They lose them to silence — a missed birthday, a forgotten catch-up, a conversation that never happened.

WhoKin is the private relationship coach that makes sure that never happens to you. Add the people who matter, set how often you want to stay in touch, and WhoKin does the rest.

NO ACCOUNT REQUIRED TO START

Download and begin immediately — your kin data stays on your device. Create a free account whenever you want to back up to cloud, sync across devices, or share a kin with a partner.

KNOW WHO NEEDS YOU TODAY
──────────────────────────────────────

Your dashboard shows exactly who's due for a message — sorted by how long it's been, not alphabetically. No guessing. No guilt. Just the people who are waiting to hear from you.

AI CATCH-UP — BEFORE EVERY CALL
──────────────────────────────────────

Tap any person before you call or message them. The AI refreshes your memory with what they shared last time — their job change, the trip they were planning, the name of their dog. You always have something real to say.

Runs entirely on your device. No data leaves your phone.

SEND A WAVE — NO MESSAGE NEEDED
──────────────────────────────────────

Not sure what to say? Send a wave. They get a personal page that says you're thinking of them. No pressure, no small talk. Just a quiet signal that they're on your mind.

NEVER MISS A BIRTHDAY
──────────────────────────────────────

Add a birthday once. WhoKin alerts you 7 days early and on the day — with an AI-drafted message ready to personalise and send in seconds.

──────────────────────────────────────
SHARED KIN
──────────────────────────────────────

Staying close to the same person as a partner, sibling, or co-parent? Create a shared kin group. Your catch-ups, notes, and reminders stay in sync — so you're always on the same page. (Requires a free account.)

──────────────────────────────────────
PRIVATE BY DESIGN
──────────────────────────────────────

Everything you store in WhoKin — names, notes, memories, phone numbers — is encrypted on your device before it ever touches the cloud. Not even we can read it.

Free and Pro users: all AI features run 100% on-device. Zero data shared with any AI service.

AI+ subscribers: opt into cloud AI for deeper insight extraction. Your choice, always.
