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.

Great Training App!

Very simple but useful timer app for building custom training routines. Worth the money!

Great timer app

Works amazing and love using it! Wish there was Apple Watch app

So easy! Love it.

I was trying to do my workouts with my timer on my phone. Disaster. I had to move the phone from floor to desk so I could see it. The screen would go black. Ugh. This app changed everything. My workouts are efficient now and I can focus on what I'm doing instead of the timer. The countdown is great! Also, it's super simple to program from week to week which I thoroughly appreciate!

Best timer ever!!

My go to app for interval training, very reliable. Does stop playing the cues when you get a phone call or use Siri but it's bearable. Only wish that they made an app for Apple Watch.

Invaluable tool!

Seconds is an invaluable tool in teaching middle school physical education. We are able to create and share, timers, circuits and other workouts with all of our colleagues. When using seconds, I can set up the activity and not worry about the clock or stop watch. This allows me to give the students more individualized attention and instruction.
