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.

Love it. I use for a yoga practice

I love this application. It let me program my yoga practice. Setting the time and the music I love. Also the volume of the music. Higher volume for the exercises and lower volume for meditation dor example. I just start the app and enjoy it.


I Approve

The app is very user friendly, useful, and effective. I’ve used it for years!


Seconds Review

Great app, as a trainer I use this often to keep workouts timely and efficient


Mission Critical App

Essential app for any and all tabatas.


Best timer period!

Great timer! The customization of this timer is second to none. Literally you create timers for anything, rest periods, color swapping for easier transition. Different buzzers for different ques.


Great timer app!!!

Just what I needed!!


Best timer

Took abit to navigate the app but once i got used to it, its one of the best timers for fitness and boxing


Excellent Workout Assistant!

The Seconds Interval Timer helps me stay timely with my workouts. I love that you can make your own custom timers, as well as the 3 second countdown before the next interval to get ready. What really helps is the “3 beeps plus 10 sec beep” option in some of my timers that helps me get ready for my next interval if I need to adjust the equipment I’m using. Lots of options to do what works for you! Highly recommend getting the pro version if you’ll use the app a lot! 😊


An enduring classic

Ive been using Second for at least 8 years, and it hasn’t changed much in that time - it doesn’t need to, its a perfect app.


Great App for Workouts

I have used the Seconds Pro app for a few years and love the ability to set up time intervals for both walking/running and strength training intervals. Very easy to use and set the interval times.


Feature request

Please make it so that when I leave the app for a few minutes then come back the interval counter and timer is not reset. I like to be able to know the sum of all the intervals I have done in the entire day. Great app for practice questions in medical school and keeping pace. Text to speech is something only this app offers for the interval ending notification. Rich with features— other interval timers didnt work. Could be used for wokiny out. I would love to be able to leave my practice wiestion timer, do an interval workout, then come back to the practice questions without lost progress of my counter.
1) dont let the progress be lost for my current session if I go yo another app for a whole (opt-in feature so it doesnt disturb others)
2) let me pause an interval for a while, work on another interval timer, then come back later and resume the session. (Opt-in feature so it doesnt disturb others)


Worth the cost

The ability to custom-add intervals with whatever exercises you want, the audio-only prompts, etc. are worth the cost. I haven’t used most of the features and I still think it’s worth it. Great app.
