Contact Book vs Google Contacts: which one keeps relationships warm?

Google Contacts started as the contact list for Gmail and Android, and it has stayed exactly that. Its job is to keep names + numbers + emails synchronised across your devices so when you tap a name in the dialer, it works. That's a real job, and it does it well. It is the canonical address book on roughly half the phones in the world.

What it isn't: a place to remember the texture of a relationship. There's no field for what we last talked about. There's no place for a gift idea. There's no follow-up nudge two weeks before your friend's birthday saying "you mentioned wanting to send flowers". The phonebook does not care whether you've spoken in three months.

Contact Book sits on top of your address book and adds the parts a real personal CRM needs. Each contact has a conversation log, a notes thread, an activity timeline, life events with reminders, gifts given and received, relationships ("brother of", "boss at"), pets, and a stay-in-touch cadence that surfaces the right person when it's time to reach out.

None of this is exotic. People with strong relationships have always done it - they kept a paper diary, or a notebook by the phone, or a private spreadsheet that they were vaguely embarrassed about. We just made it pleasant to keep, fast to log, and live across your devices.

Google Contacts exports a Google CSV directly from the web app. Drop the file into the Contact Book import dialog and every name, email, phone, address and birthday lands as a contact - including the notes field, which becomes the seed of the conversation log. We never touch the upstream Google account; what's on your phone keeps working unchanged.
