ContactFixer solves a small but annoying problem: your iPhone contacts are a mix of formats. Some numbers have the +1 country code, some have area codes in parentheses, some are just ten raw digits. iMessage, FaceTime, and third-party apps all behave better when numbers are in a consistent E.164 format — and ContactFixer gets you there in seconds. HOW IT WORKS Tap Scan Contacts and ContactFixer reads through your entire contacts list, identifying every US phone number missing the +1 country code. It shows you a full preview — contact name, old number, and new number — before changing anything. When you're ready, tap Apply All Changes and every contact is updated instantly using Apple's native Contacts framework. WHAT GETS FIXED (708) 555-0142 → +17085550142 312-555-0198 → +13125550198 8005550167 → +18005550167 17085550031 → +17085550031 Numbers already beginning with + are never touched. Your international contacts stay exactly as they are. COMPLETELY PRIVATE ContactFixer has no backend, no account, no analytics, and no ads. It makes zero network requests — you can run it in airplane mode and it works identically. Your contacts are read and written using the same native framework Apple's own Contacts app uses. Nothing ever leaves your device. SIMPLE BY DESIGN There's nothing to configure. No settings, no subscriptions, no account to create. Scan, review, apply — done.
