Contacts Manager - Phone Book is a new way to organize and customize your contacts and business cards in one convenient app. This iPhone application offers unique features not found in other similar apps. Users can store private contacts from the default app or create their own, store business cards with front and back scan images, and pin favorite contacts for quick access. Additionally, it allows users to recover deleted contacts, export contacts as vCard or CSV, sync contacts and business cards securely, and set up various authentication methods for added security.

With options like setting up PIN, fingerprint, or Face ID authentication, users can prevent unauthorized access to their contacts. The app even captures a photo of intruders trying to access with incorrect PINs. Users can also set security questions for easy PIN recovery and back up via email. Contacts Manager - Phone Book supports customizable contact layout (list/grid) and offers a dark mode theme for a personalized experience.
