## What is Vertex?

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.

FULL CONTACT MANAGEMENT
• Call, text, or email straight from a contact card
• WhatsApp, FaceTime, and Telegram quick actions (when those apps are installed)
• Tap an address to open it in Maps; long-press any field to copy it
• Share a contact via QR code or a standard vCard file

IMPORT, EXPORT & BACKUP
• Import from your device contacts, or from a CSV/VCF file
• Export your whole address book as CSV or VCF anytime
• Create a point-in-time backup with one tap, restorable later

PRIVACY, BY DESIGN 

Duplicate detection and merging run 100% on your device -- your contacts are never uploaded anywhere, and no account or sign-in is required. Vertex is free to use and supported by ads; see our Privacy Policy for exactly what that involves.

DESIGNED FOR EVERYONE

• Works with iCloud, Google, Exchange, and local contacts
• Available in English, Spanish, French, Arabic, Hindi, and Amharic
• Full dark mode support
• iPad layout with navigation rail
• VoiceOver accessible

Download Vertex today and get your address book back under control.
