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.

If your on Crosfit

It can save you count and it keep you pumped

Excellent workout timer

The title says it all really...
Excellent variety in sounds & timers.
And a very customisable option.

I use the free one and it works a treat. The only downside to the free version is you have to re-enter your workout (customised timer) every time you close the app.

If the paid version was at lest half its current price, I would not hesitate to buy it.

What I've been looking for!!

Cannot believe I hadn't even thought to download this until today!!
Everyday essential!

Awesome For Teachers

I use timed small group rotations in my classroom and the payment for the upgrade was so worth it! I have a timer created for regular day schedule, minimum day schedule, and testing schedule. Such an amazing too! I persuade all of my teacher friends to invest :)


Excellent timer, love it!!!


Love it

Great Investment in Me

I like how simple it is.
I wish they offered a library of exercises to choose from that are cals based so that people could build all around workouts.

Excellent and fast to get started!!

May a bit pricy, and yet so easy to set up and use. Like it a lot!!

Count me as a fan!

I was looking for a good workout timer for a while. I mainly us this to create timer for things like calisthenics or other workouts that I can do in my home gym. Generally I don't find the app to lack any features I was looking for. The only issue I have had is that it can be a little tricky to navigate all of the features when creating a new workout.


Just one word to sum up this app 'MEGA' works perfectly when I'm training on my own and the same when I take classes. Had the free version works but paying for pro version means less time setting up as I have already saved all my work outs. Well worth the purchase 👍👍👍👍👍

Great app!!

I've used this app for a few years but only just upgraded to the full version. I wish I'd done it sooner!! Brilliant app, easy to save and edit workouts - this is definitely the best work out app I've had!

It works perfectly

This is a must for circuit training. I love it.
