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.

Great app!

I’ve had this for a couple months now and I love it! Well worth the ten bucks. It’s easy to add exercises and build workouts. The only thing I wish it did was let you know when you hit a pr with a bodyweight exercise, but this is a minor thing

Best lifting app out there

Can’t top this.

One bug request - when the workout is complete (all routines are finished within a set custom workout) I have a tendency to improvise and add random exercises to the end of the workout.

However, these exercises keep the same rest timer as whatever the last exercise was in your preset routine.

Am I missing something? I wish I could change the rest time right in the middle of the workout.

Thanks, love you guys.



Fantastic app!

Use it everyday for my workouts!

Best app

Best workout timer app available, worth the price

Love it. Keeps me disciplined

I create custom routines for stretching and planking. It forces me to hold the duration of each stretch or plank. Being able to have music play in the background is bonus motivation.

I imagine this would be great for anyone that has PT routine as well.

Great app for working out

See above!

Great app!

This has to be in the top 10 of App Store apps. We use it very frequently for basketball practices and it helps keep us on task. The developers make frequent updates.

Update: anyway to add an auto iCloud sync option in the settings?

Great job!

Awesome workout out!

Best workout app I’ve ever tried. Exactly what I’ve wanted to build my personal workout program.

I use this for teaching kickboxing and it is awesome!

Just started using again. Love all the flexibility.

Really like this app. Just started using again after months of no exercise. Timer I use the most is a simple 30 second repeat for my stretches no matter what I do. But like that I can tailor the others for specific hit routines that I use. I have not had any issues.
