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.

genuinely useful

The app has just the right feature set, in a functional UI. best of all, it’s a one-time purchase and doesn’t force a login on the user.


I’ve been using this for years

I love this app it’s my bread and butter for my workouts


Incredible For My Weekly Workouts

I was looking for an app that would allow me to build somewhat detailed timers for working out at home. Not only does this app allow you to do that, but I can pre-build my entire workout day by day for the whole week and I don’t have to think so much about how much time is left, what’s next, or how many sets remain. My only tiny critique is that I wish it let you track how many times you’ve used a timer, as I have seen other apps do that and it would allow me to track my weekly fitness goals easier. All in all though, really great!


Excellent app!

So easy to use and to create your own workouts. Reliable and bug free. You can't go wrong!


Great timer

Enables me to enter my workouts that I’m going to do for my YouTube channel!


Great, needs shortcut to Exercise list

Worth every penny. Needs a shortcut to a library of saved exercises. When adding exercises, there should be a way to select from existing ones instead of creating a new one every time.


Flexible timer

This allow me to make custom timers where in an have different timers depending on how time I have to work out.


LOVE THIS APP

As a personal trainer this app is perfect for setting up my own timed workouts for my clients. I absolutely love it. I don’t need any other. Been using it for over a DECADE.


Ease of use

I love that I can create my own timers that fit my age and work out plan. You guys are awesome!!!


Best option, stop looking

I upgraded my Apple Watch in order that I could keep using this app past IOS26. I don’t like subscriptions. The voice prompts mean I don’t need my phone. It is feature rich and flexible - eg I use it for my work pomodoro. I’ve tried all of them and this one suits me best


Excellent

Great for circuits! I really like the ability to customize timers!


Thank you for a great App

Absolutely the greatest! Because? Because It’s my coach for doing my morning stretches and exercises. And, if I didn’t have this app I would not do my morning stretches and exercises. Sociologically It gives me a beginning and the end. Very important in order to persevere.
