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.

Great app!

I use this app to track my rest times. Fast, convenient, and easy to use!


Great for all sorts of workouts.

Interval, EMOM, with or without rest. This app does it all. Large numbers and colours make it easy to read and interpret from a distance. I use it for all my workouts.

Easy synchronization of all timers between devices with the backup feature.

The accompanying watch app is awesome. All my timers on my wrist if I forget to bring my phone. And the Quick Timer allows for an easy setup of an interval timer on the fly.


Simple and Customisable

Just what I needed!


Works as intended

Use this app almost weekly. Love it.


Update for HIIT w/Count

I stopped using Seconds for a little while because it was difficult to perform the workouts that was to reps instead of time. However, since the last (or the one prior) update, I noticed that I can now do so (workout to reps instead of time).

What will prevent me from rating this 5 stars in the future is the lack to incorporate a calendar to maintain a history of the workouts...be it through the app itself, or linking a calendar to it specifically...I need just a little more!


Best app I could find to time workouts

This app has allowed me to tailor workouts to my specific needs. I went through four other timers before settling on this app. It is easy to use, highly customizable and the developer is quick to address any problems.


Fantastic App!!

Upgraded to the pro version & have been using this app for the last six months. Fully customisable, easy to use & the ‘copy paste’ feature is really convenient. Great app!


Very good timer

And worth spending a bit of money for this. Being able to create lots of different sorts of timers is useful and provides more than what the standard free timer apps offer. Definitely recommend


One of my favorite apps ever

So many uses.... best interval and workout timing app ever


Easy to use.

I love this app and how easy it is to put together my own workouts for the best possible results. I recommend this to all my friends that exercise and anyone who wants to start. The sample timers are great and having the time right on the screen as you complete each set is awesome. Thank you for the creation of this app and helping me reach my goals.
