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.

Best for HIIT

Great for HIIT took my fitness to a new level

Can't do my workout without this timer!!!

Where's the watch integration? App could easily run on the Apple Watch and use haptic and pulse tracking to generate more useful information.

easy to use

very easy with lots of options

A very handy app for exercise routines

Well worth the $4.99 price. I had been using a $20 Gym Boss interval timer which was clumsy to set and control, this app is so much easier and has lots more custom features. It also allows you to program and store multiple timers for different routines and have them ready and waiting whenever you need them.

Worth the upgrade

I rarely upgrade if there is a free version of something but having a stack of different workouts saved and being able to pick one and go within seconds is well worth £3.99.

Does what it says

I use it for hiit workouts and it's ideal. Sets the intervals up, loud alerts and nice touch with delay before it starts

It's free people, for free this is great


Limitless possibilities to design your own workouts; helps you focus on workouts and not worry about the timer!

I'm really loving this app!

I'm really loving this app! I have only been using it for a week so far, but it's been working beautifully for what I want to do with it. I love that I can make a custom timer that's exactly the way I want it. So far I've made a custom HIIT timer and a circuit timer both custom to what I want to do and for how long, etc. I was looking for an app that would play my workout music but also talk to me and tell me what was next in the circuit or when to switch back and forth in the intervals between high and low. This does all that and so much more! I did go ahead and upgrade and paid the $5 one time price so I could save my timers. They don't take an inordinate amount of time to create, but I didn't want to have to do it every day. Plus, with family sharing and the paid upgrade, my high school daughter can use the app and my timers too. She hasn't downloaded it yet so I'll have to update later on how well the timer sharing worked. Thanks for making such a great, useful, and versatile tool!

Great app!

Love this app, use it for interval training, BBG workouts, running intervals, etc.
If I can make TINY request (read: begging you to put this in the next update!), it would be to make this app compatible with the Apple Watch!! I hate having to get my phone out of my flipbelt to skip an interval or make any changes to my timer. Pretty please!

Best timer

Love it!

Best App

Love this app. Best I've used and worth the upgrade. Does exactly what I want. 👍

Really simple to use

The app is really simple to use and super effective, you can customise it to do exactly what you need with beep or verbal warnings. If you get the paid for version you can save as many circuits as you like. I'm pleased with my purchase :)
