In their own words
Contact Book
Contact Book is a personal CRM for capturing contact details, logging interactions and keeping track of gifts, life events and follow-ups. Profiles can hold emails, phones, companies, addresses, birthdays, social links, food preferences, allergies and how you met someone. A shared screen brings together profiles, a relationship graph, a timeline, life events, gifts, follow-ups and a journal. Users can import and export information, export everything or delete an account through self-service settings. The service is available on the web and offers HTTP API, CLI and MCP access to the same data and access rules. The operator says its application servers and database are hosted in Germany. Public endpoints use TLS 1.3, database disks are encrypted at rest, and backups are encrypted before leaving the primary host. Daily database snapshots are retained for 30 days, stored in another physical location, and restore tests are performed quarterly. The operator says it does not sell user data or share it with advertisers. Contact Book has a free plan; Standard costs €10 per month or €100 per year. Email and calendar sync are not offered.
KeepContact
KeepContact is an iPhone personal CRM for people who want to remember relationships and follow up deliberately. Users choose how often to connect with each person, then receive reminders when that interval has passed. Contacts can be grouped into circles such as family, friends, and work; calls and meetings can be recorded with notes, building an interaction history. The App Store listing also names voice memo transcription, business card scanning, relationship statistics, Siri Shortcuts, calendar suggestions, and home screen widgets. KeepContact works offline without requiring an account or login. Its maker says names and notes remain on the device, with optional synchronization through the user's private iCloud, and says the app uses no analytics or advertising trackers and does not upload imported contacts. Contact and microphone permissions are optional. The listing says AI summaries and message suggestions use Apple's on-device model and that notes are not sent to a server. The app is iPhone-only and requires iOS 26.2 or later. Its free plan is free, with up to 15 contacts and three reminders; Pro options include monthly, yearly, and one-time payment plans.
