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 App

Very versatile.


This little app is shockingly great. So far so good. Still setting up my work outs. But great app so far

Clean app with all you need

I like this app for a few reasons. Firsty, the UI takes some getting used to, but there was thought involved with making it an efficient experience to log your workouts. Secondly, I like the option to add new lifts and delete old ones. Finally, it's just 10 bucks to get all the features. No subscriptions, just a flat fee.

I love this app

Works great for rounds on the heavy bag. I alternate between kettlebell swings, rest, hitting the bag I like how Apple Music playlists work with it.

5 stars

Perfect easy to make customized workout timer. Great for HIIT or any workout. I love all the options and that it takes less than 30 seconds to have my timers ready to go for the whole workout. I use while listening through headphones with a podcast or music going at the same time and it works perfect. Highly recommend.

I love this app

I use this app for everything from interval running to Tabata resistance training and gym workouts. I really love this app. You can design any kind of workout that you want and make it very specific to what ever your goal is. It’s very customizable and has so many features I don’t even understand all of them. I especially love that it syncs between my iPad and my iPhone and that I can use it on my Apple Watch. I really love it and I use it regularly!

Apple Watch Fail

Can not be used with Apple Watch also tracking a workout so therefore it’s useless.
Wish I never bought premium!

More than I expected

I had about 10 different apps on my phone to get the job done before I found this app when I was just looking for a simple timer. I can make entire workouts and it’s right there with me the whole time to count it out and tell me what’s next. Perfect app!



Great app, user friendly. Well worth buying the full app!

Motivating and Fun

This makes interval training so enjoyable! Enough built in optons to keep it interesting but I also love customizing different workouts using my favorite playlists for intensity, moderate, warm up and cool down. I find it very effective and fun, so much that I can’t wait to work out.

Perfect for what I need!

Use this at the firehouse to keep our workouts on track. Love the app!
