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.
East to use. Customizable. I’ve created a couch to 5k interval training program, HIIT workouts, and timed lifts. You can run the timer behind the scene so I can watch a movie while running on the treadmill an it alerts me of the changes audibly with a countdown. Great product. I’ve been using for years.
Love how you can keep workouts on the app. Love the cuing on countdowns.
Seconds Pro earns an 8.0 for its masterful execution of a simple premise: interval timers. Onboarding is refreshingly frictionless—no unnecessary permissions beyond notifications. The interface prioritizes utility over ornamentation; large, clear buttons and a straightforward layout make setting timers intuitive even under pressure.
Performance is impeccable across devices—no lag, smooth animations, and efficient CPU usage that won’t sap your battery during extended sessions. Offline functionality is robust, ensuring timers run reliably without constant connectivity.
Privacy shines here—no tracking, no data collection beyond what’s essential for core features. Sync across devices is seamless via iCloud, respecting user data without third-party interference.
Monetization is fair: a one-time purchase unlocks all features, avoiding subscription traps. Design avoids dark patterns, though the color scheme could offer better contrast for low-vision users.
Minor quibble: limited customization options for advanced users. Still, for its primary purpose, Seconds Pro excels.
Verdict: Highly recommended for anyone needing precise, reliable timers. Power users might crave more features, but casuals will find it perfect. Keep it installed.
I’ve been using this app for 8+ years. I bought it after a few tries and now store all my workouts on it. Like how easy it is to edit and move timers around and make compound timers. This is definitely a no frills app but a very solid option to save your workouts and drills
Great app to keep you on track. Easy to use and very useful.
Can use it for emom and tabata for KB workouts
Best timer app for teaching group fitness classes of ANY style. HIIT, boot camp, Tabata, circuits, 60/45/30 etc. Totally customizable with all the best options- alerts, music, colored timers etc. Very user friendly!
A great resource and raining for my first had marathon
I am a long-time user of this app. Love it!
I’ve been using Seconds daily for years, mainly for workouts but also for other uses. It’s easy and reliable.
I’ve used the Seconds timer for YEARS and loved it! Whether I’m using it for skate intervals, Spin Intervals or recently Rebounding intervals, It’s been great. Being able to screen cast my timers onto a bigger screen so my older eyes can see across my workout room has been SO essential! I LOVE this update! I’ve also started to send interval timers for my family to use online. I just send them a link!
I’m 69 and workout twice a week with a professional trainer. But I have multiple timers customized for my in-between days. It definitely helps keep me strong and healthy to deal with my 15 acres, large house, animals and large family.
