Who hasn't been there? Many contacts have telephone numbers, email addresses or postal addresses stored in different orders. Sometimes your private number is at the top, sometimes your business number – or even a fax number that you hardly ever use. Every time you need to check carefully before dialling. That's now a thing of the past. Bring order to your contacts! With Contact Sort, you can sort the contact fields (telephone numbers, emails, addresses, URLs) exactly as you wish – for individual contacts or for all at once. Even individual fields that you have created yourself are taken into account. This means that the right information is always at the top of the list. FEATURES - Sort phone numbers, email addresses, addresses and URLs - Sort individual contacts or entire contact groups - Field search: find contacts by specific numbers, email addresses or text content - Dark mode for more comfortable use in low light - Dynamic font sizes automatically adjust to your iOS settings - Completely redesigned with SwiftUI for modern operation, stability and speed DATA PROTECTION Your contact data remains exclusively on your device. There is no online transmission, no tracking and no storage outside your iPhone. The data is only used for sorting purposes.
