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.

Exactly the app I was looking for!!!!

Have used this app for a week so far and it has all the features I was looking for in a timer!!! Have not found anything I don’t enjoy about this app. It’s easy to use and set up.

Great simple gym log

I am new to weights and gyms and this simple app both reminds me what to do next and logs my progress.


This app is seriously awesome for anyone that enjoys interval, HIIT, or circuit training!! You can customize every time to even say which exercise you’ll be doing! I just started using it and I’m so excited to explore it more and more!

Always is. Always has been reliable.

I will continue to use this app as long as it runs as smoothly as it has since day 1.

- different options for tones and countdowns

- works with the apples iHealth

Fantastic App

This is an incredibly useful app for any kind of workouts that require interval timing. I use it for interval running, hiit, and my tabata workouts. I love the voice prompts. They allow me to seamlessly go from one exercise to another. Keep up the good work!


It is a very useful tool for me, both at work and at home.

Excellent, flexible

Great app, does everything you'd want and probably more. I have found a sequence I can't put timers to yet. Strongly recommended. Worth every penny.

Great for my music practice

I use this for organising my trumpet practice,it helps me make sure I cover all the elements I need to do each week so that I don't spend too much time on things I shouldn't. Great app and a bargain

J gray foyle

Worth every penny!

Terrific timer. Versatile and well thought out. Definitely motivating when working out.
