Clean up the contacts already on your Mac. Merge duplicates card by card, fix hundreds of contacts at once with a preview, and undo any change. One purchase, no subscription, and nothing leaves your Mac. CLEAN UP • Find duplicates by name, email or phone, even when one number is saved with its country code and the other without. • Merge them card by card in Merge Studio: keep the value you want for each field, choose the account, and undo later from Merge History. • Health Check scores your address book from 0 to 100 and lists missing names, invalid phones and emails, and repeated values. FIX MANY AT ONCE • Bulk Edit names, companies, phones, emails, addresses, birthdays and groups with text or regular-expression changes. Every change is shown before it is saved. • Edit any field in the editor or right in the table, including nickname, name prefix and suffix, social profiles and the photo. FIND AND ORGANIZE • A fast, dense table with the columns you choose. Sort any column A–Z or Z–A; dates sort by date. • Search names, companies, emails, phone numbers in any format, addresses, groups and, when you allow it, Notes. • Colored tags saved as Contacts lists, so they sync with iCloud and Google. Smart Views with ALL or ANY rules. • The Command Palette opens any contact, view or action from the keyboard. UNDO AND RESTORE • History keeps daily encrypted backups on this Mac and shows what changed, field by field. Revert a field or bring back a removed card. • One-click vCard backup, and a restore that adds back only the missing cards. IMPORT AND EXPORT • Export a selection or a Smart View as CSV, vCard or Excel. Review every card before a vCard import writes anything. • Print Avery labels and envelopes from any list. NEW IN 2.0 Merge Studio with colored accounts, Health Check, History and Backup, Tags, Rules, birthday reminders, Labels & Envelopes, Excel export, editing for every field, sorting by any column, smarter phone matching, a menu bar search and, on macOS 26, Apple Intelligence note summaries and plain-language Smart Views. PRIVATE BY DESIGN Your system Contacts stay the source of truth, and macOS keeps syncing your accounts. No ads, no analytics, no sign-in, no contact cloud. Contacts and Notes are processed on your Mac and never uploaded to us.
