HIIT (High Intensity Interval Training) is a method well known to burn fat in a short & intense workout. And there are many different ways to it : sprinting, crossfit, running, bodyweight workouts, cycling, yoga, stretching, weightlifting, boxing ...

High-intensity interval training (HIIT) is an enhanced form of interval training, an exercise strategy alternating periods of short intense anaerobic exercise with less-intense recovery periods. HIIT is a form of cardiovascular exercise. Usual HIIT sessions may vary from 4–30 minutes. These short, intense workouts provide improved athletic capacity and condition, improved glucose metabolism, and improved fat burning.
This definition comes from wikipedia (http://en.wikipedia.org/wiki/High-intensity_interval_training) where you can find a lot more informations. It explains some very popular program, like the TABATA. HIIT is also a common practice in Crossfit trainings.

You can use it during all trainings with intervals or other timed repetition

Basically, this is how it works : on the first screen you will set up your workout phases durations (preparation time, work, rest, rounds and cool down) and you will choose your sound.
Then hit “Go !”, work and just follow the sound… or the voice !
You can listen to your own music, just make sure you can still hear the sound.
At the end of the workout, a new feature allows you to share your workout with your friends on Facebook and Twitter @hiit_android

Now automatically pause and resume if a phone call arrives.
This is why PHONE_STATE permissions are required. But the app never collects and stores phone numbers from users phones.

Love this app! It makes working out HIIT style so much easier. I don't constantly have to be looking at my watch or setting alarms. I can just focus on my music and the exercise. The voice tells you when to GO and REST. You set the number of rounds, seconds of rest, and seconds of work. Plus the "Congratulations you have completed your workout" at the end is always nice.

I have been happily using this for years (paid version). But not I've noticed a bug: the volume no longer is persistent when I change apps. For example, I start a workout in a quiet room, then the volume way down using the slider, switch to another app, and when I return, the volume had reset back to loud. This is repeatable. I'm using a pixel 4a.

I have used this app for several years and liked it very much. However, this morning I discovered it has been updated and all my saved presets were erased. The volume was also set to maximum, which was not appreciated by my wife who was still sleeping. Appears to be a case of "fixing" something that wasn't broken. I'm running Android 9 on a Galaxy S10e. I've also noticed that the volume level is no longer saved between sessions.

Thank you for your feedback. I am sorry that your presets got erased. This has been reported but we have not been able to reproduce it. Could you tell me what phone and android version you are running? This would be useful to help us fix the problem.

What's new

This release fixed an issue reported by user who are running Android 11 where the application was covering the phone navigation buttons.
