Zones - Time Zone Tracker is a versatile app designed for iPhone users, developed by Necati Aydin. It falls under the Utilities & Tools category and provides a convenient solution for tracking people across different time zones. This app allows users to add and manage unlimited time zones, customize their names and availability timings, and easily identify who is available at any given moment.

With color-changing cells indicating availability status, users can quickly determine who is reachable, potentially available, or currently unavailable. Additionally, Zones offers the flexibility to personalize the app with different color themes and fully supports dark mode for iOS 13 users. For enhanced customization, users can opt for Zones Plus, an in-app purchase unlocking additional features like unique app icons.
