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.

Best HIIT App

Best HIIT app avail IMHO. Simple, elegant, and very customizable. Highly recommended.


Excellent app

Excellent, so flexible, lets me create my own workouts colour coded for muscle groups. I know how much time I have to workout and what groups I need to train one glance and I can pick the workout I have created and get going.


Fantastic—with one request

This app is fantastic. i’ve wanted an app like this for a long time for my interval training, and boom. here it is.
The only thing that would make it better would be integration with spotify. I have fantastic playlists that i only wish i could integrate into the app and line up with different blocks of my workout


Simple, Clear, and Does the Job!

Really handy app! I use it for my own circuit training and cool down stretches. It’s simple and intuitive to set up multiple timers, and I love that the numbers are big enough to see from across the room. Makes my workouts so much easier. Highly recommend!


The best exercise timer

I have used this app for years and have all my favourite timers built in. It’s easy to use and intuitive, and I like how you can even have them tell you what’s coming up next.


Love this app

I have been using this app for the past 6 years or so.and I love it. I create workouts everyday, keep them to modify and use again. This app is proving to be an invaluable organizational tool for my new YouTube channel. I use it when creating my videos and for keeping track of the workouts I intend to record and those that are completed.


Great app all around!

I use the app for boxing and HIIT Circuit training. I love how the text to speech calls out each round or interval based on what I put into the text. The music add on is a plus and makes the work out so much better.


Great at its job

I never pay for apps. But I did for this one, and I don’t regret. Simple, does what it says. Love it


Love it!

I use this app professionally and love everything about it. Great job to the developers.


No frills, simple to use

I wanted to convert my favorite treadmill routines into a timer, and this is perfect for that. Straightforward and easy. Also love that it’s a one time payment vs a subscription, that alone would make me support this company with their other apps


Great for Circuit & HIIT.

Easy to use. Great visual aid while working out. Not full of unnecessary options, very straight forward.
