Coleva vs Contact Book

Coleva is an iPhone personal CRM and relationship journal that organizes short written or dictated entries into memories about people, places, and moments. On-device intelligence extracts people, relationships, dates, and details, with a one-tap undo. A living map shows connections in colour-coded groups, while search can answer plain-English questions from the user's notes. Birthday lead-time reminders and check-in nudges help users follow up. The Free plan is limited to 20 people and includes journal capture, the living map, birthdays, and Ask Coleva. Coleva Plus adds unlimited people, important-date reminders, calendar-synced nudges, AI assist, career and location trails, photo avatars, app lock, and custom map colours. Plus costs $3.99 a month or $39 a year. Notes, diary entries, relationships, and attached photos are stored locally on the iPhone; the maker says it has no server holding user content. Optional Cloud Assist can send limited text or profile information to OpenAI's API when enabled in Settings, and can be turned off. Coleva requires iOS 26.0 or later.

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.
