Add the people who matter, remember when you last contacted them, and get a quiet reminder when it may be time to reach out. KinKeep is made for a small, meaningful circle: close friends, family members, relatives, mentors, or anyone you do not want to lose touch with. You can save last contact dates, relationship type, notes, contact methods, birthdays, and birth years. If you only know part of a birthday, keep just the part you know. Use KinKeep when you want to: - remember to contact friends and family - track when you last called, texted, or checked in - keep birthdays and birth years in one private place - get gentle local reminders without turning relationships into tasks - stay in touch without importing your address book - keep your people and reminder records on your device by default With KinKeep, you can: - add friends, family, and other important people - organize people as friends, family, or other - remember roughly when you last connected and review contact history - save birthdays, birth years, and approximate ages - turn on private birthday reminders - see one reminder at a time in Today - choose Contact Now, Just Contacted, or Remind Me Later - open your chosen contact method directly - adjust reminder timing and remind-me-later options KinKeep does not read your address book or chat history, and it does not decide who matters for you. It simply helps you remember last contact dates, birthdays, and the people you mean to keep in touch with.
