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.

text-to-speech makes this app for me!

The text-to-speech feature makes this a killer app for hands-free AND eyes-free workouts.
Also great to see the Apple Watch support added in the latest version.


Fantastic app couldn't do without it

Awesome App

Super helpful. Takes all the time tracking off of me so I can focus on exercise not time. Use it multiple times a week.

What a time saver!

I have twin toddlers and time is absolutely precious! My custom work outs are saved in the app and the timers are all set up! It's awesome, thanks!!

Glad I upgraded

Purchasing the upgrade was a great call. It has changed my exercise for the better.

Great time for a workout

This timer is very easy to use and save workouts,you can title each workout and save reps as often as you need- best timer I've used...!


Easy to use, very flexible, great interface, love it. Thanks! Update: Still fantastic, better than ever!


Works great for my circuit exercises!

Excellent app

I work out alone quite often and this app makes the workouts much more fun and efficient.

Great app

Used free for a while before upgrading, good app

Superb interval exercise app

I use it for New York Times 7 minute workout, advanced 7 minutes, and Body for life 20 minute running intervals. I know of no other program that gives you this level of flexibility to define your intervals. Highly recommended!

Best timer app!

I've tried a few free interval timer apps and this is by far the best and easiest to use...it's worth paying for as the free version doesn't let you save workouts. Couldn't live without it now!!!
