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.

Gym on the go

Really good alternative to a gym if you are traveling/ abroad.




Excellent timer - easy to customize. Have tried many - this is the best in my opinion. Would be awesome if it connected to apple health data for workouts!

Great app!

Love this app!


Able to do the 30-20-10 interval workout without looking at the phone! Can change streaming playlist. Game changer.

After Paying...

It's a good app for tracking my workout and keeping me on pace. I play music in the background through another app instead of their option. Just because it's not easy to use. Can't be confusing.

Absolutely Love It!

You don't have to look at your phone it reads aloud the workout names. Saving workouts makes it easier you can just get straight to it

Use it every day!

Not only is it perfect for intervals, but makes a great timer for planks and other times exercises. Recommend to everyone.

Great app!

Love this for circuits, HIIT workouts and treadmill sprints- easy to use, especially with the preprogrammed timers! Also love the fact that I can customise the music too! My only gripe/request would be the same as others- an Apple Watch add-on, where you can see your current exercise and time remaining on your watch would be really useful!

Excellent- The Best!

I've bought a few of these and this the best. This app is easy to use, allows you to create custom timers and routines. several samples are are setup to get you up and running quickly. in addition, this app allows you to play you favorite music while the timer is running and calling out the exercise

Great way to work out on the road

This is great to have on your phone and get circuit training in while in a hotel room. I also program the circuits from some of my fav videos so I can watch tv while accurately completing the workout.


My physical therapist recommended the Seconds app for timing my physical therapy exercises at home. I ended up purchasing the full version almost immediately when I realized what great capabilities it has. I love the ability to create custom timers for various mixes of exercises.
