Seconds is an extremely popular, and highly versatile interval timer app for High Intensity Interval Training (HIIT), Tabata and circuit training workouts.
Download Seconds for free on iOS or Android and try all it's features. A one time in-app purchase for the Seconds Pro upgrade will allow you to save your timers rather than recreating them each time.
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.
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.
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.
Seconds provides plenty of options for how you listen to your music while you workout. A few options include:
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.
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.
Seconds Interval Timer will continue to alert you of interval changes whether in the background or the foreground.
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.
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.
I have used for years mostly for creating custom mobility workouts but also sometimes just for timers for planks or back holds. App is easy to use.
I looked up interval timer this morning and tried Seconds for free, based on ChatGPT recommendations for my needs. It was very easy to set up exactly what I wanted in an exercise program. 7 warm up exercises, 60 seconds for each exercise, with the software announcing each exercise. I will use more of the features as I go along, but this was easy to get started with.
App disappeared from watch 😔
Hi,
Both my sister and I are experiencing the same issue with the Seconds app on our Apple Watches — it shows a yellow warning triangle and won’t open anymore. It used to work perfectly before the latest watchOS/iOS update.
Is this a known compatibility issue, and do you plan to release an update soon?
Thanks in advance for your help — we really love the app and use it daily for our workouts!
I'm giving this five stars because it's a very good app but still has problems in iOS 26.1 and my new apple watch series 11.
The apple watch complication is installed properly but I simply cannot find it when trying to add to a watch face. I scroll through all the complications but cannot find it. I've rebooted both iphone and watch, deleted and reinstalled but to no avail. I hope this gets fixed.
I’ve been using this app for years now, simple to use and very effective. Unlike other apps that try to do everything, this is just a log for your workouts.
This app is a lifesaver for timing group fitness classes! But the latest update has some issues. My watch no longer vibrates at the halfway point of an interval and there’s no longer a vibration countdown at the end of an interval. It’s also not possible to access the copy paste buttons on the new iPhone interface. I hope these issues get resolved, because this is an amazing app.
This is one of the rare apps that gets used constantly. I have timers for workouts, meditation, training sessions , nearly everything I need a time for this app delivers
Love the app so much however I think there is a bug on it since the update please help!
I love using this app, makes me workout so efficient
Feature request. It would be great if the sound in other apps will not be dipping when there is notification from this app.
Just leave the beep, don’t make the music/sound from other apps shallower. Thanks!
Been using it for almost 10 years!
