Vertex: Merge Contacts

Is your address book full of duplicate contacts, half-filled entries, or the same person saved three different ways? Vertex finds and fixes it -- in minutes, entirely on your device. WHY VERTEX? Saving contacts across WhatsApp, Google, iCloud, and email leads to duplicate chaos: the same person with three different phone numbers, a nickname next to a full name, work and personal emails scattered across separate cards. Vertex's on-device AI spots the duplicates other "exact match only" cleaners miss, then lets you merge them safely - with a full undo if you change your mind. KEY FEATURES SMART AI DUPLICATE DETECTION A 4-tier matching engine scans your address book to spot: • Exact matches - identical phone numbers or email addresses • Fuzzy matches - similar names (e.g. "Jon Smith" vs. "John Smith") • Nickname pairs - "Bob" ↔ "Robert", "Bill" ↔ "William" (same last name) • Organization matches - contacts sharing a company or work domain REVIEW BEFORE YOU MERGE Nothing merges without your say-so. Preview exactly what the combined contact will look like -- pick Smart Merge (AI chooses the best field from each contact) or Manual Merge (you choose every field yourself). 1-TAP UNDO Merged something by mistake? Every merge is backed up automatically, so you can roll it back with one tap from Backup & History. CONTACT HEALTH SCORE A 0–100 score for your whole address book, plus a list of exactly which contacts are missing a phone number or email so you know what to fix. RELATIONSHIP GRAPH See how your contacts connect -- grouped by shared organization, family name, phone number, or email domain -- in an interactive visual tree.
