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.

World Class Routine

For years I have been trying to have what I call a World Class Routine but with things getting in the way and not really truly creating a habit, I was never able to do it until I found this app! Thank you so much!

Works as Promised

Th preset HIIT & Sample Timer workouts are great to give you an intro on how effective it is to use Seconds for training. A little challenging to create my own workout rotations at 1st, but was able to create my workouts & don’t do them w/o this app running. Highly recommend!!

Unusual use case

Love this app. I actually use it for timing practical exams.
It lets me set a reading timer, an examination timer and give a one minute warning. All with voice prompts giving the student instructions.
As a freelance tutor I am often working alone so don’t have anyone to run timings for me and this does the job perfectly.
Thanks dev team!!


Great app. Dose exactly what is says on the tin. Really easy to setup your own routine

Does everything

I’ve tried various apps to track my workouts in the gym and found this to be the most complete. There is a slight learning curve, but once you get the hang of it, it’s simple to use with all the features you could ask for. Well worth the money.

Well designed

Super flexible and customizable, the templates help you create personal timers, fun to use

Best Weightlifting App Ever

Finally found the app that’s perfect for tracking my workouts. Well worth the money spent. So many ways to setup your workouts.

Great App!!

This app is definitely worth the price. The customization and easy user abilities allow me to make workouts on the breeze.

Excellent app!

From work out intervals to setting big blocks of time to practice music, this app has seriously helped get stuff done!

Time blocking

I’m using this app to time block my morning routine and my work day because I’m so bad at keeping myself on track and on task... it’s been SOOOOOOOOO helpful with this!!! Love love love it!!!!

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. Day 1! Thank you for making this app so intuitive.

So far....

I tried the 7 min one already in free app and thought it was great. So I decided to upgrade. Why? So I can make my own interval workouts. I use Pinterest for ideas, then build my own. I really like how the timer keeps me moving. Without a timer, working out in my home gym turns into a half day thing while I keep stopping to do other things.
