Zones is a time zone tracker that allows you to keep track of people in other time zones. The vibrant color-changing cells allow you to know who's available in different time zones.

- Add Unlimited Time Zones: Name them, rename them, and choose the timings of availability for each time zone. 

(This app allows you to use 2 time zones for free. You can unlock unlimited time zones with an in-app purchase.)

- Know Who's Available: Color changes show who's available, who might be available, and who's not available.

- Themes*: Change the color theme.

- Dark Mode: Zones completely supports dark mode for iOS 13.

- Custom App Icons*: Choose from different app icons.

*Some features require Zones Plus, an optional in-app purchase that unlocks these features and supports the continued development of Zones.
