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.

Best interval trainer

Love everything about this app.

Great Timer

Love it, use it twice a day for morning yoga & afternoon bootcamp.

I LOVE my seconds Pro!

I use this app every single day. It is SO easy to use and has virtually every format option for all different workouts. I use it to teach my fitness and yoga classes as well. It's great!

Great for Circuits and HIIT

I use this app for my circuit and HIIT session; it has now become an essential training aid. The free version offers some great functionality and should suffice for the majority of users. The only reason to pay is if you want to save your workouts. Both are compatible with Spotify / iTunes so you can listen to music whilst also hearing the timer. All in all - a good timer.

Huge Value Add

Seconds Pro has been a wonderful find and has vastly improved my solo fitness routines. I love doing HIIT runs in the park so the voice timer is especially useful - no more checking my wristwatch or phone! Love the ease of use and ability to change up workouts as I please. Thanks second pro for making working out more easy and enjoyable!!

Superior Timer

Easily customizable timer that you can use to make your own interval, circuit or HIIT timers. Also has some sample workouts in there using kettle bells, body weight exercises and cardio components. The purchase of the pro version is well worth it to be able to make your own workouts. I would love to see the ability to simply copy an exercise and paste it though when making your own workouts. Maybe the developer will add this?

Great functionality

Awesome interval timer. Allows the creation of custom sessions and music under each section. Highly recommended.

Versatile and effective app!

The App delivers more than I expected. A bit more pricey than others, but when I thought of the price differential, it was the price of a fancy coffee! My spouse purchased another timer, and regrets not having chosen this one.


Very good timer, got cut copy paste which makes things faster. Lots of options!

Best workout app ever

This app is superior to anything else. The background audio is fantastic.
