Friendships rarely end with a fight. They just grow cold.
A new job, a move, busy weeks. Nobody leaves on purpose. You just reach out a little less, until “We should catch up soon” has turned into a whole year.
Keep, the app for your friendships
You decide how often you want to hear from each friend. Keep reminds you when it's time, and remembers birthdays and what matters to your friends.
Free for iPhone and Android. Local on your device, or on all your devices with Cloud Sync (Pro).

Most of us don't lack contacts, we lack the overview: who hasn't heard from me in a while? Keep keeps that overview for you.

The number lives in your address book, the birthday in your calendar, the gift idea in some note and the last conversation deep in a chat. None of these apps tells you when you last talked or what's on your friend's mind right now.
This is where Keep comes in
Every friend gets a profile with birthday, important dates, notes, gift ideas and your contact history.
You decide how often you want to hear from someone. When a friendship drifts away from the fire, Keep gently reminds you. No pressure and no guilt.
After a meetup, call or message, you log the contact with a single tap. Your friend moves back to the fire, and the next reminder only comes when it's time again.
This is your home screen in Keep: by the fire sit the friends you're in rhythm with. Whoever is overdue drifts to the edge and into the dark. The more friends sit in the warmth, the bigger your fire burns.
Every contact earns warmth points and unlocks small extras for your friends, like a scarf or a guitar. Pure decoration, no real money.
Import contacts from your address book or add them by hand. Free for up to 15 friends.
Put each friend in a circle. The circle decides how often Keep reminds you: Intimate weekly, Personal every two weeks, Social monthly, Public quarterly. You can adjust it per friend.
When a contact is due, you get a notification. You reach out, log it with a single tap, and your fire grows.
Keep is a quiet place for the people who matter. No feed, no likes, no noise.
See at a glance who sits close to the fire and who needs some warmth right now.
Birthday, notes, gift ideas, hobbies and your contact history in one place, instead of spread across many apps.
Weekly, monthly or less often. You decide per circle and per friend.
Everything important about your friends in one place, instead of spread across calendar, address book and chats. Keep does the remembering, so you can focus on reaching out. The core features are free; Keep Pro adds Cloud Sync and AI insights.
Weekly for family, every few months for old school friends. Keep nudges you when it's time, and not more often.

The campfire is your home screen. Every friend sits as close to the fire as your contact is recent compared to the rhythm you want. Whoever hasn't heard from you in a while drifts into the dark. The size of the fire shows the warmth of your whole network.
Every logged contact and every well-kept profile earns warmth points. They level up your friends and unlock gear like a scarf, cocoa mug or guitar. With the embers you earn along the way, you buy fun extras for their avatars. It is pure decoration: embers cost no money, and you don't have to take part.
