NestContacts

A calmer address book for your Mac. Find duplicates, sort people by role, country and city, keep birthdays in view — and every change reaches iCloud, Google and Exchange through Apple Contacts.

Beta on TestFlight — coming soon

Requires macOS 15 Sequoia or later.

Duplicates, sorted out

Finds the same person saved twice — transliterated names, old numbers, nicknames — and merges them with one click.

Filters that make sense

Role, sphere, country, city and priority. Combine them to find exactly who you need.

Your accounts, unchanged

Two-way sync with Apple Contacts, so iCloud, Google and Exchange stay in step. A backup is made before anything is deleted.

See who is on Telegram, open chats from a card, add missing photos and people you only know from Telegram.

Birthdays and favorites

A calendar of birthdays and a tile view of the people you call most.

Private by design

No accounts, no servers, no analytics. Everything stays on your Mac. Read more
