The Interval Timer is a fully functional interval training timer. It allows you to specify an overall workout time as well as a Low/High intensity interval and rest time between sets. During the set, it will alternate between the high and low intensity intervals helping to increase stamina. This is perfect for cycling, running, lifting weights, stretching, boxing, MMA, martial arts, circuit training, etc.  The sound themes let you tailor the sounds to your desired activity.

Asymmetrical intervals are easy to set up so it is easy to workout with Tabata intervals ("High Intensity" = work, "Low Intensity" = rest). You can set the intervals to the same duration for symmetrical intervals.

Working out to music is not a problem. Start you music playing in the iPod app, then start IntervalTimer. The sounds will play over top of your music without interrupting it.

Usage

- Example: Set the 'Total Time' to 4 minutes, 'Low Interval Time' to 10 seconds, 'High Interval Time' to 20 seconds, and the 'Rest Time' to 1 minute. Next, set the 'First Interval' to 'High' and press 'Start'. The Interval Timer will then alternate between 20 seconds of High Intensity and 10 seconds of Low Intensity for 4 minutes, giving you a 1 minute rest between sets.

- You can turn off the rest period by setting the time to zero.

- In the iPod App, begin playing a playlist, then go into the Interval Timer and begin your training. The music will continue playing while you train.

Troubleshooting

No sound

There are 2 common causes of no sound being produced on the iPhone or iPod Touch:

iPhone: The app respects the ringer mute switch and the ringer volume. Make sure that the ringer mute switch is not enabled (top-left of the side of the phone) and that the ringer volume is turned up.

iPod Touch: The app does not use the internal buzzer/speaker but rather plays through the headphones and/or speakers when the iPod is docked. In your iPod’s ‘Settings,’ under “General” > “Sounds,” make sure that “Sound Effects” is set to “Both.”

Crash When Running

The most common cause of this issue is a bad installation. Trust us, we wouldn’t release an App that crashes right away; that is just bad practice. To resolve this, remove the App (press and hold its icon and tap the ‘X’ that appears to remove it), then re-download it from the App Store (when you re-download it, it will ask for your password and then tell you that you have downloaded it previously and you can re-download it. You will not be charged again.) Wait for the installation to complete and try to run the App again.
