CardHop is from the Fantastical folks, and it’s basically Fantastical for your contacts. It offers some good power tools and customization to search, create, and reach out to your contacts. For example, when searching for a contact, you can change the default messaging option to apps like Telegram or WhatsApp. Ditto for email.
One great option is that it can create contact groups and smart groups. This is especially useful for iOS users since, even after 13 versions, Apple’s Contacts app stillcannot create groups. These groups are created in your contacts database, so Apple’s app will recognize them and sync to your other devices.
To create a contact group on iOS, tap All Contacts at the top of the app, then scroll to the bottom of your groups to find the Add Group button. On a Mac, mouse over the name of your contacts account to display the (+) button.
