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.

Recent Customer Reviews

Really good interval timer

Agree with other reviewers that it is much better as a paid for app. The free version has I guess deliberately frustrating limitations. But it's worth the money. Good job!

Great app, I used it for my experiment!

It's easy to use. And it's a great lab assistance!


A great timer application that allows one to configure individual event timers, nest timers within timers, announce countdowns and events during the timed period.

Just excellent for establishing the repeating routines necessary for Physio post operation recovery exercises. Allows the patient to run thru the exercises without a second person being there all the time .... Essential to time and call out countdowns ( 5,4,3,2,1 rest for 10 seconds etc etc) without an app like this.

Highly recommended.


very very good app, I love use this.. can I use this app on Iwatch!?


Free is ok. But you. We'd to buy Pro. Really good app for workouts, stretches and HIIT sessions. Easy to use and you can add details to each section. Pleased with the purchase.


When I saw the price of this app, I almost balked at buying. I couldn't imagine paying more than a $1.99 for an egg timer which is essentially what I thought I was buying. I couldn't have been more wrong. This app is amazing and I love it. I would buy it again and I would pay full price again and again because this app helps me do the thing I love doing with the least amount of fuss.

Great app

Solid timer app!

"Seconds" to none

Excellent app - worth every second!

Everything I need in a timer

I used this for my own and client's training sessions. Every now and then the music component doesn't play even though I set it to play. But that could be due to me having too much going on with my iPad. Actually I haven't tried using a timer w/ music since the update. So it may work perfectly fine now. I have several timers saved from two years ago and I never have issues with any deleting.

I am very pleased with this app. It makes my training much easier. I would definitely recommend going pro. There is no better option. Just realized there is a compound timer option and am too excited about it. So much so I had to write this review.

Update: this has improved a bit. Plan a workout ahead of time and press play when ready to go. I usually listen to Pandora during workouts. I still like it and the pro is worth it

Best and most customizable interval timer around

As a coach of Weightlifting and CrossFit, and a follower personally of the Gymnastic Bodies program, I've got a million uses for a workout timer. I tested many of the options out there in the App Store and none were as versatile as Seconds Pro! I literally use it daily!


Does exactly what you hoped it would do. Love it!
