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.

Use for Football Practice

This app is awesome for what we do at football practice. USB C adapter to HDMI and we display it on big screens. Save from buying a $4000 timer. Bluetooth music to speakers and we are rocking with the segments being called out by the app. Only bad part is we can’t see the segment number. Wish we had an option to make it the same size as the time.


Very Helpful

I use this for my bike training and also for elliptical workouts and find it very easy to use and easy to customize. I like being able to change the background colours for an extra visual of what part of the workout I am currently doing. It does exactly what I was looking for when I tried a few similar apps.


Best timer

Seconds is a great timer - it is flexible and allows me to use the voice and sound to do the exercises the Physio recommends without having to stop and look at paper or watches. Fantastic


Simple and elegant

I appreciate apps that do the one thing that you’re looking for and do it well. No added razzle-dazzle but just the amount of flexibility to get it to do what you want. I’ve been using it for several years now for daily stretch routines after workouts.👍👍


Best in its class

A well designed, easy to use app. No bloat, no nonsense. Just the functions you want done elegantly.


Does what it says

No bloatware, does exactly what it says. Cannot see how it can get any better


LOVE this timer app!

I have been using this for many years and it’s definitely my go to to create personalized timers for literally anything that I’m doing not just workouts.


Fantastic app

I have the free version and will eventually level up-it’s great for me and my group classes!


Useful For Many Things!

I have been really enjoying Seconds for the past year for so many things; Pre-pregnancy circuit and strength training pre/post marathon, prenatal exercising, and contraction simulator. I highly recommend for so many things, again, not just exercise!


Amazing app

I use it for my breathing exercises - and the biggest advantage is that the alert sounds work even if you have other apps open and even when listening to videos - which most apps don’t have


Love this

It does EVERYtHING including now ready my exercises so I don’t have to see the screen to know what’s coming. Only timer you need.


Game changer!

Game changer for my OTF coaching - love the ability to copy intervals, color code and assign vibration so I don’t have to look at my watch at halfway points. Would love a few more color choices.
