Our timer is the perfect companion for your next intensive workout. It’s the successor of our successfull tabata timer app!

We included a bunch of new features for you:
- complete rewritten version that supports the high resolution screen of your iPhone.
- You are now able to change the interval type. We provided +5 intensive interval presets for you
- three different tone sets (voice and two other options)
- choose the color, you like
- visualization of the intervals with three nice graphics designs
- the app does not sleep/lock while in use
- you are able to hear your itunes music in the background

High intensive interval training (HIIT) is one of the most effective training principle today. It combines two of best known training methods in one time-efficient way:

the first ist high-intensity training, that pushes to get a maximum effort to achieve muscle fatigue and to consume maximum oxygen in a quick burst. this is measured to one’s VO2 max, which is the highest amount of oxygen, your body consumes during exercise. Working close to your VO2 max triggers the afterburn effect, where the body continues to consume more oxygen up to 48 hours after the workout.

the second is interval training, which alternates periods of intensive effort with periodes of short breaks / low-intensity effort. This boost metabolism significantly longer than a steady workout of equal or greater length.

Needs a screenlock

This app needs a screenlock desperately. When I try to use it while my phone is in my hand (running, or using headphones, for example) it's IMPOSSIBLE not to make contact with the screen, which pauses the app or changes the settings on the slightest contact. This is basic stuff. Please add a screenlock or, if there is one, make it easy to find.

Apple Watch and Background Execution!

Like the new UI, although the name and the look was so different that I didn’t realize that it was the same app at first.

I would love to have the app running on my Apple Watch and have it tap me when I need to start and stop the exercise.

One other feature you really need on iPhone is the ability to run in the background. So I can turn off my phone screen during the exercise. Saves my battery and keeps me from hitting the buttons by accident.

I don't know why everyone is complaining

I truly don't understand why everyone is whining about the update. The PRO is well worth the money and you have different sets. Tabata, metabolic, gladiator, superset, etc. You can change the color and the look of the timer. More features for what you already paid for. If you can't take 10 seconds to find the timer you want, then why are you working out? That's pure laziness.
