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.

You Can’t Beat It!

It’s worth every penny to pay for the ability to save custom timers. This app puts your entire workout on auto pilot. There are several different timer templates and a custom option. I’ve had this app for years, it’s the one to get.


Amazing!

This app is exactly what I’ve been looking for. It makes my workouts super easy to plan and I love the timers.


Ideal Basics

Keep it simple… or make it complicated. Seconds has you covered.


Great App

Awesome app to keep you on track with your workouts


What a hidden treasure for the ADHD world!

I have a formal diagnosis of AuDHD (combined type), and I recently decided to use this app to support me in my day-to-day life.
For the past two years, in my world, setting timers for focus, work, and rest — using a Tabata-style approach — has been truly groundbreaking. I genuinely believe this app is more than just a fitness tool. Through its thoughtful defaults and the way it feels almost like a supportive companion, it has become an indispensable part of my daily living as a neurodivergent person.


Exactly what I needed

This is the best workout timer I have found! Works great!


Very useful app

I’ve tried it first before purchasing. It’s really worth the money and it’s not that expensive. I use this app for my warm-ups before playing the guitar, before going to the gym or some stretches while at work or not doing anything.


Good app for basic timers

Easy to use, good basic features for everyday applications


Best and most reliable app for training

Been using seconds for years, I have hundreds of different options for circuit training, dynamic and fight style training….. I highly recommend using seconds to help improve cardiovascular and conditioning for all types of training


Best Tabata App

I’ve tried a handful before finding all of the features I need in this app. The flexibility is the best part for me. Whatever I want to do the app can do. Love it.


Simple, but effective

I’ve used the Seconds app for a few years now, and I really value its capabilities. It’s got a simplistic UI, and requires a bit of work to set up your timers, but its versatility and customizations are worth the effort. I’ve used mine for couch to 5k interval planning, kettlebell swing timers, planks, stretches, and many other simple but important routines. I’ve yet to come across another app that’s let me have this much control, rather than following preset routines that may not fit what I want to do. Highly recommended.


Fantastic app

Have used this for years for my interval work. Really recommend
