Templates for HIIT, Tabata and circuit training

Seconds comes with templates for common interval programming allowing to build advanced timers in a matter of moments.

If the templates do not fit your needs you can use the custom timer to build your timer one interval at a time. You can even combine and loop through many timers using the compound timer.

Speaks your interval names

Often when working out you just want to keep your phone in your pocket and get on with it. But if you are doing a circuit involving many intervals how do you remember what's next?

Seconds will speak your interval names, so this is never a problem. There is even an option to let you know what the next interval is so you have time to prepare before it starts.

Soothing alerts

If you are looking for a mediation or yoga timer text-to-speech or high pitch beeps may not be appropriate. For situations like these Seconds comes with more soothing alerts such as bells and gongs, or you may wish to have no alert sounds at all, or just a vibration. All these options are available.

Music the way you like it

Seconds provides plenty of options for how you listen to your music while you workout. A few options include:

  • Assign songs to intervals
  • Play a playlist throughout a set
  • No music during your breaks
  • Shuffled album throughout the entire timer

Of course, if none of those suit you, you can simply listen to your favourite music player in the background and Seconds will play it's alerts over the top.

Import and export your timers

Importing and exporting timers from Seconds Pro could not be simpler. Just select the timers you wish to share and hit Export. Timers can be sent via email or AirDrop (on iOS devices).

Timers can even be shared with friends that don't have the app via the web sharing function. Once shared, an online timer will be created for anyone to use on any device.

Runs in foreground or background.

Seconds Interval Timer will continue to alert you of interval changes whether in the background or the foreground.

Color code your intervals

Colored intervals are great when you just need a visual clue to see which interval you are on and what is coming up next. Seconds displays the the whole screen in the current intervals color, apart from the next interval which uses it's own color.

Seconds has 10 colors to choose from with an advanced option to customize the colors if you wish.

Vertical and horizontal timer display

Seconds utilises all the available width for the main timer display so it's easy to read at a glance. By default it displays the interval time remaining, but can be configured to show total time remaining, or elapsed times.

Variety and function!

The second timer give me many options for rounds (boxing, circuit, HIIT, TABATA - which was new to me). I even changed "exercise one" to "side plank and diagonal push-ups" and Seconds pronounced those words correctly. We do have to teach it Japanese (for karate) hahaha!

Excellent - does exactly what I'm looking for.

Excellent for all types of circuit, HiiT, Tabata or interval training. Worth every penny.

Easy to use!

I love being able to plug in my workout for day and not having to think twice about the timing. Lots of options for different types of workouts!


Love this app. I use it for Tabata sprints and for circuit timing. I travel a lot for work, and this app helps me bust out short, intense workouts I'd never pull off without it.

Don't be cheap and try to get by with the free version. Sure, it's free, but to have to type in your workout every time? We're talking about a couple dollars here, and the developers of this app deserve it for doing such a good job. So skip tomorrow's chocolate double latte iced frappuccino and you'll be able to buy this app for yourself and a couple friends.

Very good and Useful

I like to set different timers for different exercises. This timer works correctly. I have some for pool exercises and some for squats and lunges. I set them different depending on how slow I want to do the exercise and how long to hold it. It also keeps count of the reps.

Get the heart racing!

This app is perfect for designing your own hiit workouts with all your favourite exercises. Simple to use and very customisable, but with templates and samples for the main styles of hiit workouts as well. Tabata is my new favourite! My kids love it too - they design their own 'workouts' with backing music from itunes and loads of somersaults and cartwheels. My only slight gripe is that it mispronounces 'push' and 'push-up'.


This app is absolutely perfect for customized interval training!
