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.
As a personal trainer and sports coach, I use the features on this app very frequently. Easy to program timers for group sessions, or simply staying on task with a client.
Great timer options, can create combo timers, easy to program, amazing number of voice options to choose from, have used it for years.
Super easy, simply but does the job with simple beeps or a voice for a more specific workout.
This is an outstanding App. It’s simple enough but has a fair amount of customisations. It works seamlessly in conjunction with iPhone and Apple Watch
The Pioneer in interval timers. Simple and easy to navigate the app. I’ve had this app for years!
I’m happy with everything in this app. Great job to the developers . I’m the Head Brazilian Jiu-Jitsu Coach @UFC Gym Mililani, in Hawaii.
Nice HIIT features
Use for timing lots of different exercise regimens. Easy to use and versatile.
Very useful, an essential well done.
Easy to create great workouts, lots of options
This is the best timer on iOS and a good price.
I really do love this app, I even bought it. But it keeps bugging me to rate it so that's why I'm writing this so it will stop bugging me. But I would recommend it anyways. I've downloaded a lot of timers , never bought them cuz they sucked. But this is the best out there by far. It's like 5$ but it’s worth it.
UPDATE: 4/20/2025
Even though I’ve wrote a review, it keeps asking me to write another one. That’s super annoying. I bought it, now I just want to enjoy it and be left alone.
