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.

Excellent - slight changes

Brilliant - best app for logging workouts. Needs to be updated to be able to include supersets / giant sets etc


Good app

Good


Excellent timer

Perfect for when I’m on my spin bike. I just wish it would automatically log the date and time upon completion of each timer. Also, iCloud syncing would be nice, as sometimes I use the iPhone, sometimes the iPad.


Best timer app out!

This app is so easy to use and versatile, i highly recommended it


Just what I needed.

I wanted an app that was easy to use (didn't want to spend extra time on my phone logging workouts), would let me easily customize workout routines, produce visual progress report and would tell me when I hit a new PR. HeavySet did all this and more. I love the app and I'm glad I purchased it.


So good

So so good. In an App Store cluttered by junk this is a gem.


Terrific For Running

Great app. Easy to use. Love using my own music.


Mom of 3 loves

This timer is amazing. I can create different workouts based on the time I have and my kids really enjoy doing the workouts with me. I put my iPhone on our big tv so we can hear the timer and notifications. This has allowed working out in my home with no equipment to be possible and fun!


Great app - Would be awesome if there was cardio too

Awesome app - it would be great if there was a way to track cardio as well.


Comprehensive and Lean

Great tracker. My number 1 pick from my Strong exodus. Everything you need and nothing you don’t. Only requests are the ability to more quickly log RPE/RIR and a simpler layout to review sets (e.g. the database-like layout of strong or Strongur)


Perfect

The best timer I’ve found for interval training. Well worth it!


Glad I bought it

One app that I’m glad I bought. Great for setting up intervals.
