Persodex vs. Dex
Your relationships, your data …or someone else's server?
Both Persodex and Dex help you stay in touch with the people who matter. The difference is where your relationships live.
Dex is a cloud CRM. It imports your network from LinkedIn, Gmail, and Facebook into its own database - powerful, but your contacts, notes, and conversation history sit on third-party servers.
Persodex takes the opposite path. It builds directly on the contacts you already own in Apple Contacts, keeps every note on your device and in your private iCloud, and never sends a single byte to our servers. There isn't even an account to create.

Why people choose Persodex
No new database to maintain. Dex creates a second copy of your network that drifts out of date. Persodex enriches the contacts already on your iPhone - edit a number anywhere, it's current everywhere.
Privacy isn't a feature. It's the architecture. No servers, no account, no tracking. Your notes about friends, family, and colleagues are nobody's business - including ours.
Pay once, keep forever. Prefer not to rent your address book? Persodex Pro offers a lifetime option alongside monthly and annual plans.
When Dex might fit better
Honesty matters: if you live in LinkedIn and need automatic job-change alerts, email sync, or Zapier automation across thousands of professional contacts, Dex's cloud approach serves that workflow. Persodex deliberately doesn't connect to those services - that's the price of true privacy, and we think it's worth it.
