# Keep App > Keep is a free friendship management app for iOS and Android that helps you stay in touch with the people who matter most. Using smart reminders and relationship circles based on Dunbar's Number research, Keep fights the loneliness epidemic by making it easy to be a reliable, present friend. ## What is Keep? Keep is a personal relationship manager built for friendships — not business contacts. Unlike CRMs that treat people like sales leads, Keep helps you remember what matters: birthdays, life events, and the small details that make your friends feel valued. Your data stays on your device. No ads. No tracking. Forever free. ## Key Features - **Smart Reminders**: Get notified when you haven't been in touch with a friend — not just on birthdays, but based on how close you are. - **Friend Circles**: Organize contacts into Intimate (5), Personal (15), Social (50), and Public (150) circles based on Dunbar's research on human relationship capacity. - **Friend Profiles**: Store notes, gift ideas, hobbies, and important life events for each person. - **Relationship Dashboard**: See your network health at a glance — who needs attention, upcoming birthdays, and overdue connections. - **Birthday Tracking**: Never miss a birthday again with automatic reminders. - **Offline-First**: Works anywhere, no internet connection required. ## Key Facts - **Price**: Free — no subscriptions, no hidden costs - **Platforms**: iOS (App Store, ID: 6757089043) and Android (Google Play, com.keep.mykeepapp) - **Privacy**: 100% private — all data stored locally on device, never sold or used for advertising - **Science-backed**: Based on Robin Dunbar's research on the cognitive limits of human social relationships - **Version**: 1.0.2 - **Languages**: German (primary), English ## Why Keep Exists 21% of adults report feeling lonely. 49% have fewer than 3 close friends — double the rate since 1990. Chronic loneliness has the health impact equivalent to smoking 15 cigarettes a day. Keep addresses this by removing the friction from staying in touch: instead of relying on memory, users get gentle reminders at the right time, for the right people. ## Frequently Asked Questions **Is Keep free?** Yes, Keep is completely free.
