About this app

Seconds is widely recognised as the best interval timer for HIIT & Tabata training for mobile devices and is recommended by celebrity trainers and personal trainers to their clients all around the globe.

Non-paying users may create as many timers as they wish, but once an interval timer is started it may not be used again. Upgrading to the full version removes this restriction.


• Large, full screen, color coded display that is easy to read from a distance. The display works in either landscape or portrait.

• Templates for HIIT, Tabata and circuit training. A custom template to create every interval. And the compound editor where you can combine many interval timers into one.

• Speaks your interval names so that you can follow a workout without seeing the screen at all. Seconds can even provide prior warning of the upcoming interval. Other alerts including beeps and bells are available.

• Coordinate your music with your Tabata workout. Each interval can have its own music assigned allowing you to match the intensity of your music to the intensity of your HIIT workout.

• Seconds runs in the background allowing you to either have your display off, or use other apps while the HIIT timer is active.

• Export and import. Share the Tabata timers with friends or download them from the web and install them in Seconds.

I have an S21. The scroll button when selecting a song for a step is much to small to grab and scroll. I also need the option to stop the songs/playlists from repeating themselves like the iPhone version of this app if I want to rate 5 stars. There's a lot of features missing from the iPhone version that make it hard for me to love this app. Why can't I speed up the voice? Why is the step text cut off on the timer editing screen? What I do like is that the music doesn't stop playing otherwise.

I used the free version for a few months before realizing that the full version would be worth it to me. The many customization options and modes are great, and I definitely think it's worth the price if you're planning on using it more than a handful of times. I couldn't figure out how to sort and organize the different workouts, but the developer quickly responded with directions when I reached out. The only thing I would change would be a color selection wheel or more color presets.

I like the flexibility of being able to really customize anything I want with this timer, and the templates that allow some things to be done fairly quickly. I like the Text-to-Speech so I don't have to look at it for every interval. I would like it better if when I tapped in the field labeled "Exercise 1," I didn't have to backspace to delete all that before typing what I want the field to be called. But it's been very helpful.
