Why did we create another timer app when there are already dozens in the App Store? Because “Timer Z is the Last Timer You’ll Ever Need”! It's simple to use yet full featured. For example, you can easily set a timer to give a 15 seconds warning before another alarming at 1 minute mark. Some unique features of Timer Z are: - A simple count down timer can be set and started with just 3 taps - Multiple timers can be set and can run simultaneously - The timer will fire even if the Timer Z app is running in the background - Each timer can be named and set to expire after a time interval, or at a specific point in time like an alarm - While a timer is running, it can show remaining time or elapsed time since start, either in full hour/min/sec or just seconds - Background graphics shows the percent of time remaining - A running timer can be paused and resumed to continue where it left off - When a timer expires, there is a choice of alarm sounds, vibration, or no sound at all - Optionally the alarm can continue to sound until acknowledged - Upon expiration, a timer can start another timer, including itself in a loop - Timer activity history is saved and can be emailed, great for record keeping - Timer data can be saved and loaded from a linked Dropbox account Whether you’re looking for a simple timer, or one with all the bells-and-whistles, Timer Z is the best choice! NOTE: this version is limited to 2 timers. Use the convenient in-app purchase of Pro feature to add an unlimited number of timers, and eliminate all advertisements.
