AppAdvice has teamed up with Runloop in order to offer you a chance to win one of five promo codes for Seconds – Interval Timer ($2.99) for iPhone and iPod touch.

Whether you’re looking to get back into shape through high-intensity interval training or you just need to keep track of those cookies in the oven, Seconds – Interval Timer should be your go-to app. Seconds is a clean and simple programmable timer. It includes six premade timers to choose from, or you can create your own down to every last detail.

When creating a timer you can choose from a HIIT, Circuit, or Round template, or you can start with an empty timer and add everything from scratch. Timers can be customized to include an unlimited amount of intervals, different colors for each interval, specific songs or playlists for each interval, vibrations, and more. You can also create and save as many timers as you want, and copy and paste timers to avoid having to input the same information over and over again.

Six intervals to go!

Seconds works great in portrait or landscape orientations, with the latter featuring a large and easy to read timer that can also serve as the stop and start button. The app also includes the ability to lock the display in your favorite orientation, and is able to run in the background even when the screen is locked.
