Quick timers, user defined custom timers, and clocks with Zulu and world times. Timers count up, down, even repeat, and on expiration can flash, beep, vibrate, and show popups or notifications.

The Clocks screen shows Zulu and local time (which are also at the top of the Quick Timer and Custom Timer screens). Use the default time zones or select your own.

The Quick Timer screen features easy to use timers that are simple to set and use. Tap the arrows to set and then tap the timer to start.

The Custom Timer screen allows you to create and save your own timers that can count up, down, or even repeat. Set your own names, times, colors, and display order.

Customize the appearance of your clocks and timers by choosing from 24 colors. (Over 700 colors available with in app purchase.)

App alerts you on timer expiration with audio (if selected) and by flashing the affected timer to get your attention. You can also get alert popups if the timer is not on your current screen, or receive a local notification if TimeStruct is in the background or the device is locked. (Note: iOS has a limit of 64 simultaneous local notifications per app.) If using an iPhone, you also have the option of getting a single vibration for alarms and alerts.
