ContactsPlus vs
Dex

Dex is a personal CRM built to remind you to follow up. ContactsPlus is built to keep the underlying contact data correct in every account you own. The clearest expression of that split is sync: Dex’s own core-features documentation says it transfers your Dex contacts to Google Contacts “in one direction”, and Dex connects no Apple iCloud account at all. ContactsPlus syncs Apple iCloud, Google and Microsoft together, two-way, on every paid plan.

Only through a beta. Dex’s Contact Sync writes to Google Contacts in one direction. Its Two-Way Contact Sync is a CardDAV connection to a device address book rather than to a provider account, its own page says “This feature is still in beta”, enrollment is by emailing Dex to join the beta users group, and its published limitations say special dates such as anniversaries aren’t supported and custom fields won’t be synced to Dex.

No. Dex’s Sync Features list covers LinkedIn, Google, the two-way device sync, WhatsApp, phone calls, iMessage, Instagram and Outlook. iCloud appears only as a one-time import flow in the mobile app, and there’s no iCloud account connection anywhere on the site. ContactsPlus syncs iCloud two-way alongside Google and Microsoft.

Not contacts. Dex’s Outlook integration is email and calendar: it updates the last interaction from your mail and meetings and shows relevant threads and events on the contact. Its own page states that Outlook sync is available only on the Dex Professional plan. ContactsPlus syncs Microsoft contacts two-way on every paid plan.

No. Dex’s own pricing page says every plan starts with a 7-day free trial, and its entry plan is Premium. ContactsPlus Free is free forever: one synced account, 1,000 contacts, and the full contact record including notes, tasks, custom fields and file attachments.

Not automatically. Dex lets you merge two records by hand, and its own card-scanner guidance when a scan creates a duplicate is to open either record and merge them, keeping whichever details you prefer. No duplicate-detection engine is documented. ContactsPlus scans your whole address book for duplicates, including the same person held in different accounts, and merges them in bulk on Premium and Teams.

Not in Dex itself. Teams are a separate Dex product called Rolodex, and Dex’s own Dex-versus-Rolodex table marks Dex with a cross for multiple users in one workspace, creating multiple workspaces, Microsoft 365 integration and creating tasks. ContactsPlus Teams adds a shared address book, roles, shared notes and assignable team tasks inside the same product.

Export first. Dex documents an export process for your contacts, notes and network updates, and doing that while your subscription is still live keeps the decision reversible. Then connect the same Google and Outlook accounts to ContactsPlus, add the iCloud account Dex could never connect, run duplicate detection over what arrives, and rebuild the follow-up habit with Tasks.
