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.

Awesome app

Love the app having to hold on to my iPhone until it is available on Android


So far have this for 2 weeks and I have to say keeps me on track with my workouts. Before this I use to waste a lot time resting between sets. Now it keeps me going and more efficient workouts. One of my better app purchases. Update on this app. Absolutely love it. Use to set a white noise sleep and meditation. Really flexible.
Wanted to update my review. I find this to indispensable for my workouts. Really works well and keeps me on track. If this is no longer supported not sure where I’m going to go. Love this app. Use it every Workout.


It’s a great app. It takes all the guess work out of your workout. If you want to rest for 30 seconds. You can do so without looking at you watch every 5 seconds. The custom workouts as well as the preset workouts are awesome. Just an awesome app all the way around.


I have used Seconds Pro for about 2 years. It is highly versatile and easy to use. It's easy to design your own special timer. Whatever your needs, this one will do it. Highly recommended. I use it paired with my Polar Bluetooth heart rate monitor.

Another year of use, it's well worth the small cost for the pro. You can design a timer for any routine you need.

I have now used Seconds Pro for about 4 years. It continues to be a great choice for a timer. It is very versatile.

Exactly what you need for any workouts

I use this for timing my planks. I use it for timing my jogs. I use it for timing everything in my workout regimen that needs a good timer.

I would love to see an option for timers to automatically add x seconds to an individual timer after x amount of uses, to help push me a little further, but I'm not sure if that's such a niche case that it'd be too confusing in the UI.

REGARDLESS-- great app, humble developers, worth the buy.

Have upgraded to Pro and all working well

Have upgraded to Pro and all working well

Awesome app!

it’s the most versatile useful timer I’ve see and used and I’ve only just scratched the surface!

Purchased the advanced

Hi all I use this app frequently I was under the impression you only have to purchase once. However a note has appeared saying upgrade can you help? I have logged in but worried this is a scam.

My go-to interval timer

I've been using Seconds since version 1, and it's been one of my most-used apps for years. I've tried at least 6 different apps and Seconds is the only one with the versatility, stability and ease of use to work for all my needs. I use it to time several different types of workouts, music practices and other miscellaneous tasks. The display is easy to read, timers are easy to set up, manage and organize. It's an excellent app.

It’s also the only one I’ve found that consistently beeps when other apps are in the foreground, when the phone is in vibrate mode and after receiving a phone call or certain other events on the phone.


Probably one of the most versatile workout apps I've used. Easy to create any type of workout. Visually simple too.

Excellent exercise app

I have used this app for 8 years now. As my exercise routines change and evolve this app has remained my mainstay because of the intuitive and flexible design. I absolutely love it!

Awesome app!

The latest version has a glitch where it keeps asking you to try the full version even though it’s already been purchased and hitting restore doesn’t rid your screen of the huge yellow banner. Part from that it’s the most versatile useful timer I’ve see and used!
