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.

Clutch

This app is easy to use and helps keep me focused when I don't want to do my own thing.


So customizable!

This app makes setting up great workouts easy!


Pleased!

Does what it purports to! With pleasing design, the right customization options, even ability to adjust design. Happy to have purchased the full shebang.
Most minor of “wishes” – would appreciate an even cleaner app icon. But hard to care much when the app ticks all the boxes!


Thank you for being proactive

We appreciate you being so responsive and actually caring about getting everything fixed! It does not go unnoticed. Thank you!


Great timer

This is a great timer for various applications


Thank you for the updates. Coaches use this!

I’ve been using this for years and they are very good about customer service. Just be careful because sometimes updates make really simple things go away (type of workout) and sometimes major things (haptics, halfway, count up). It works really well to keep track for large group fitness classes, individual clients, and yourself


Super flexible

Flexible timer, you can define your intervals, rounds and alerts. Pre-delivered timers gives you a starting point too.


Great App

Love the app! I use it for coaching and makes my life so much easier!


Great

This really is a great app to create fitness routines and an easy way to stick to them. Save workouts you like, create a challenging workout fast with presets and/or spend more time personalizing for your preference


As a fitness trainer, I would be lost without Seconds Pro

I had tried out dozens of timers before discovering seconds. It’s by far the best fitness timer out there five stars.


Live this until the Nov2025 update

This app has been great at making my timers for workouts and has synced with my Apple Watch.. HOW EVER.. the latest update the phone part works great.. the Apple Watch part does not do the countdown in the time just stays at the time . In tiny print is a timer that adds up to total time. The watch vibrates as each segment is ending .
Please fix this
Love being able to make the custom workouts and the ability to have my playlist
Easy to do and edit


Love it!
