Custom Interval Timer helps you create workout timers that guide you through your exercise routines.

Setup
You'll find that setting up a Timer is fairly straightforward. To create a Timer, you set up an Interval List. Set up an Interval List by adding Intervals to the list. Add as many Intervals to the Interval List as you'd like. Customize each Interval by giving it a name and a time to countdown from. You can cycle through the Interval List as many times as you'd like (1-99) by changing the Rounds number.
Playback Controls
Playing a Timer works much like a media player. You can play or pause the Timer. You can skip Forward to the next Interval or skip back to the previous one.
Feedback System
The feedback system lets you know where you are in your Timer. It notifies you of: the final 5 seconds of an Interval, the start of an Interval, the Round you're on, and the end of the Timer. This makes it seem like you have your own workout trainer, guiding you through your workout. You can be notified of these events by voice, sounds, and/or vibration.
The available options make Custom Interval Timer one of the best interval timer apps in the market. This customizable interval training timer is great for Running, Tabata, High Intensity Interval Training (HIIT), Cycling, Weigh-Lifting, CrossFit, MMA training, Boxing, Yoga, Stretching, Home workouts, Fitness, Pilates and much more!
