Keep, the app for your friendships

Keep the people who matter close to the fire.

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).

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.

Your calendar knows the birthday. Not the friendship.

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

Everything about your friends in one place.

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.

One quick call, and she moves closer again.

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.

The warmer your friendships, the brighter your fire.

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.

How Keep works.

  1. Invite your friends

    Import contacts from your address book or add them by hand. Free for up to 15 friends.

  2. Pick a circle and rhythm

    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.

  3. Reach out when it's time

    When a contact is due, you get a notification. You reach out, log it with a single tap, and your fire grows.

Your campfire fits in your pocket.

Keep is a quiet place for the people who matter. No feed, no likes, no noise.

  • A campfire as your home screen

    See at a glance who sits close to the fire and who needs some warmth right now.

  • Friend profiles that remember

    Birthday, notes, gift ideas, hobbies and your contact history in one place, instead of spread across many apps.

  • Reminders at your own pace

    Weekly, monthly or less often. You decide per circle and per friend.

Frequently asked questions

Anything else? Write to us at hello@keep-app.de.

Is Keep free?

You can use Keep for free: up to 15 friends and 4 circles, reminders, the campfire and birthdays. Keep Pro unlocks unlimited friends and custom circles, Cloud Sync and personality insights. Pro costs €3.99 per month or €29.99 per year and is billed through the App Store or Google Play.

Where is my data stored?

Keep is local-first: your data is stored on your device by default. If you turn on Cloud Sync (Pro), it is synced encrypted across your devices through our service providers PowerSync and Supabase. We don't sell data and don't use it for advertising. More in our privacy policy (German).

What does the campfire in Keep mean?

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.

What are warmth points and embers?

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.

Isn't my calendar or contacts app enough?

Your calendar and contacts app store single facts, like a number or a birthday. Keep brings everything you know about a friend into one profile, with notes, gift ideas and your contact history, and reminds you at the right rhythm when you haven't been in touch for a while. You also group friends into circles of closeness.

Can I import my existing contacts?

Yes. You can import contacts from your address book and then add birthdays, notes and the right circle.

What are personality insights?

Personality insights are based on a research-based questionnaire on personality, attachment style and love language. With Keep Pro you get a personal analysis. For this, only the required answers are sent to Google Gemini for analysis, and only after your explicit consent. You can try the questionnaire for free in your browser first.

Which platforms is Keep available on?

Keep is available for iPhone on the App Store and for Android on Google Play.

Who's sitting by your fire tonight?

Get Keep and invite your first friends to the fire. Free for up to 15 friends.

For iPhone and Android. Pro is optional.
