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.

Take the counting out of my training sessions

Easy set up to get your work-rest ratio controlled during your workout

Love it

Love this app. You can build it to do whatever you want and it helps keep you focused on your work out.

Of all the fitness gear I have, Seconds Pro has provided the most value.

I use Seconds Pro alone and with our boot camp group. Great little tool. Intuitive. A fantastic value.

I could have bought an expensive timer but why? This does all I need and, being audible vs primarily visual, we don’t have to stare at it. It’s pretty much dummy-proof.


I have 55 workout routines stored on Seconds Pro, from HIIT to stretching routines and everything in between. I have short and long workouts to fit my schedule. The timer keeps my workouts constant no time wasted.

Love it

Brilliant app, great way to create a workout whilst listening to music. Bright and clear timers makes it easier to train.

Very flexible

A simple app initially but it has as my complex have become mixed it still flexes to support everything. A very good app.

Seconds pro

Awesome app. Love the customization of the timers. Helps me meet my fitness goals without having to use a stop watch!

Great app!

This has to be in the top 10 of App Store apps. We use it very frequently for basketball practices and it helps keep us on task. The developers make frequent updates.

Great job!

Seconds Pro


Great app!

I love that I can customize and save my timers. I use this all the time!

A great app for fitness people

I use this app almost every time I go to the gym, whether I’m using it for a HIIT cardio session or a customized circuit. The feature I love most about it is that you’re able to still play music and have your phone locked while the timer is going.
I recommend this all the time. 10/10

Perfect for repeating intervals

I use this for asana and pranayama. The ability to program repeating intervals is hard to find on a lot of apps, but this one can handle it! Download it!
