Your personal CRM that lives on top of your iOS contacts. Your contacts app knows their phone numbers. Persodex helps you remember who they actually are. Persodex turns your iPhone's native Contacts into a lightweight personal CRM. No duplicate address book, no separate app to maintain. It syncs tags, notes, and details directly with the system Contacts app you already use every day. Never lose the story behind a relationship. Keep an interaction journal for each contact - what you talked about, where you met, what matters to them - with on-device AI summaries powered by Apple Intelligence. Nothing ever leaves your phone. Organize the people in your life. Add custom-colored tags and groups for friends, family, coworkers, and networking contacts, so you can filter and find the right person in seconds. Show up for the moments that matter. A built-in birthday calendar with countdown cards and Home Screen widgets makes sure you never miss another one. Set per-contact catch-up frequencies - weekly, bi-weekly, monthly, or quarterly - and get gentle local reminders to reach out before people drift away. To-Dos Every contact now has a To-Dos tab for the things you want to get done - send the deck, make the intro, follow up after the trip. Duplicate contacts cleaner Empty contacts, No birthday, No photo, First name only, Odd name formatting. Business Card Scanner Scan any business card and save the details directly to your contacts in seconds. Profile Enrichment: Bring a contact up to date without retyping anything. Connect a service of your choice: FullEnrich, Apollo, Enrich, People Data Labs, or Reverse Contact. Bring your own API key, then tap Update Profile on a contact to look for their current job title, company, work email, phone number, website, and LinkedIn profile. You approve every change, field by field. It stays off until you set it up, and only the contact's name, company, and any work email or profile link are sent - straight to the service you picked. Remember people who passed away Some people stay part of your life even after they're gone. A contact's Details tab now has a quiet »Keep in memory« button. Their portrait appears muted everywhere in the app, their page shows their life dates, and their birthday stays on the calendar as a calm remembrance instead of a countdown. Home Screen widgets keep the essentials visible at a glance: your Business Card QR, upcoming Birthdays, pending Catch-Ups, Favorites, a daily Greeting, and your Latest Notes. Share yourself just as easily. »My Card« gives you a personal QR business card for instant sharing, with its own Home Screen widget so it's always one tap away.
