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.

Amazing setting and set up. Allows music to be shuffled through and connected to Bluetooth headphones. Love love love.


The upgrade is worth it definitely and would work well with boxing rounds.

Just right

Easy to understand, and just what I needed

Keeps U focused

I like being able to hear what exercise I should be on

Alarm sound options, please!

This is the best timer for my daily yoga. I keep trying other apps because I want a different sound to alert me when the exercise is over. All the other timers have too much frill that make it too clunky to be flexible enough to adapt to each yoga set. It would be minimal additional code to allow the app access to the device’s sounds. Please, please, please? 😃


The fact that it speaks to me with all the drills and commands I gave it makes it a perfect training partner.
Press play, put my phone down and train away!

Worth the money!

I never write reviews on apps.. And here I am, writing one. Not only that, but I decided to write this the day after first using it.
This app is fantastic. I decided to take up jumping rope. I found a solid workout online where you have a four set warm-up, alternating between three exercises.. Followed by an eight set workout, alternating between different exercises. Sound confusing??

So I write it all down on paper.... Annoying, but whatever. Then I realize that I need to search for an interval timer because I don't have a clock in my jump rope space. I didn't want to use my phone stopwatch because I wanted it to be easy to listen to music.

I'm sure that doing all of that would have been possible, although pretty inconvenient. When the whole circumstance to starting my workout is too complicated, that's the best way to make me quit. I'm lazy.

So I spent ten minutes, setting up my customized interval workout for my new jump rope routine - pairing each type of exercise with a new song. And now I get to save this timer, along with any workout I challenge myself with in the future. What easier way to keep my workouts interesting and challenging!!

In short, Seconds is likely going to lead to a fitter version of myself. Thank you for making it!

Completely worth it

Easy to use and packed with features that make it unquestionably the best timer I’ve seen.

Great workout tool

I do hiit a lot and I absolutely love this app so much. It allows me to stay on track with my sets and helps me remain focused while I’m at the gym! Definitely recommend this app to people who love hiit or circuit training

Most Versatile Workout Tracking App

I just got into weightlifting so I wanted to accurately track all my workouts. I tried Stacked and was disappointed, and then saw this. You can customize this so easily and the app works great for the 5/3/1 program. I would recommend any weightlifter to get this app. If you’re skeptical, you can try it for free, but soon you’ll also fall in love with it.


Great app- easy to customize for any timed workout!

Six Stars!

This is perfect now.
Voice prompts & music on Apple Watch make this the perfect timer I've been looking for!
Thanks for keeping up the improvements
