A private relationship-memory app for iPhone
Kith gives each person a place for how you met, what matters now, and the dated moments you do not want to forget—without turning care into a CRM.
Closer people take more space because you set their closeness. Kith never infers it.
ConstellationSee closeness the way you chose it.
PersonKeep the context that makes care specific.
BeginStart with one real person, not an import.
Look inside
Version 1.0.0 build 3 is the latest build verified as processed and assigned to the owner's internal Personal Testing group. Current source is build 7; there is no public enrollment link.
A name in a phone is not the context of a relationship.
Kith holds how you met, a birthday, standing notes, and the dated calls, dinners, gifts, milestones, and small facts you would otherwise trust yourself to remember. It does not rank attention or turn people into work.
One thoughtful loop
The constellation is orientation, not a score. Open one person, recover the useful context, write a short dated note, and leave.
Constellation
Every person becomes a warm lantern. Its size comes only from the 1–5 closeness value you set—not recency, message volume, circle, or an algorithm. Searchable list view remains available for speed and VoiceOver.
Person
A person can hold their circle, birthday, how you met, standing notes, and a chronological log. Each dated entry stays a note, hangout, call, message, gift, milestone, or something to remember.
Begin
First-run onboarding asks for a name, the circle and closeness you choose, and one thing worth remembering. It writes through the same local person and log services used by the rest of the app.
An honest fit
A fit Kith may fit if you want to retain the small facts and dated moments that help you be more thoughtful with family, close friends, and other people who matter.
Not a fit It is not a contact book, social network, sales pipeline, messaging app, attention score, or reminder-notification product. It does not import your address book or infer who deserves care.
Useful before sign-in
Every edit lands first in one local JSON document and remains usable offline. A private CloudKit mirror stays available during the transition. If you choose a Significant Hobbies account with Apple or Google, structured people and dated notes also synchronize through the private Hub; sign-in never blocks local use.
Read the plain-language privacy policyNo. Adding people, setting closeness, searching, opening a person, and writing dated notes work from the local iPhone document. A Significant Hobbies account is optional and adds private Hub synchronization.
The iPhone holds the immediate full document. A private CloudKit mirror remains enabled during the sync transition. If you connect the optional account, Kith synchronizes structured person fields and dated interaction records through the private Significant Hobbies Hub, while preserving the local working copy and durable waiting changes.
No. Closeness is an explicit value from 1 to 5 that you set. Bubble size reflects that value only; Kith does not infer it from note recency, log volume, messages, or circle.
No. You add people deliberately. Contact-book import, messaging, photos, and notification reminders are not in the current product.
Not publicly. Kith is in internal TestFlight with no public invitation, App Store listing, paid plan, subscription, or checkout. No permanent free or paid model has been announced.
“I wanted a beautiful personal relationship-memory app that helps me stay more thoughtful about the people in my life.”
— Sarthak Agrawal, creator of Kith
Real use decides what I add next. Closeness stays explicit, and the private context has to stay useful.
