Contact Book vs Cardhop: a better address book vs a relationship memory

Cardhop is a delightful front-end for the contacts already on your Mac and iPhone. We're a layer for the things an address book was never meant to hold.

At a glance

Cardhop (from the Fantastical team) is a polished replacement for the stock Contacts app - fast search, natural-language entry, dialing and emailing in a tap, all reading your existing Apple / Google contacts. It's an address book done right. Contact Book is a different category: a relationship memory with cadence reminders, conversation logs, life events, gifts, and a family graph. Pick Cardhop if you want your existing contacts to feel great to use; pick us if you want to track the relationship, not just the phone number.

Contact Book vs Cardhop: feature comparison

When to pick which

Pick Contact Book when

You want to remember the conversation and the cadence, not just dial faster.
You're not all-in on Apple, or you share a relationship view across devices and platforms.

Pick Cardhop when

Your contacts already live in Apple / Google and you mostly want them faster to use.
Natural-language entry and tap-to-act are the daily value for you.

Two tools that don't actually compete

It's worth saying plainly: Cardhop and Contact Book can live side by side. Cardhop makes the address book on your devices fast and pleasant - it's where you go to call someone or fix a typo in a phone number. We sit one layer up: the place that remembers you last spoke in March, that her dad's surgery is this week, that you gave her a cookbook last birthday so pick something else. Cardhop answers "how do I reach this person right now"; we answer "what do I need to remember about this person".

Where the address-book model runs out

An address book - even a beautiful one - is a static record: name, number, email, maybe a birthday. It has no concept of time passing. It can't tell you that you're overdue with someone, because it doesn't know what the right interval was. It can't hold a thread of "what we talked about last time", because that's a log, not a field. The moment you start wishing your contacts app remembered context across months, you've outgrown the address-book model - and that's exactly the seam we're built on.
