MORE INFORMATION:-

• LARGE CLEAR TIMER DISPLAY AND COLOUR CODING
The timing screen has a large, clear, time display that can easily be read from a distance. It works in portrait or landscape. The current interval and next interval are displayed so you can see also what's up now and next. The entire background uses the current interval colour so you don't even need to read the name.

• TEMPLATES MAKE IT EASY TO PROGRAM
Seconds comes with templates for High Intensity Interval Training (HIIT), Tabata and Circuit Training making it very easy to quickly create a timer for your workouts. If you require more advanced options, Seconds Interval Timer doesn't let you down. You can create completely custom timers one interval at a time, or even combine timers together to create compound timers.

• TEXT TO SPEECH AND ALERTS
The text to speech option will speak your interval names as you get to them, or even give you some advance warning. Alternatively, you can choose from the built in alerts. These ranges from simple beeps, to MMA air horns and boxing bells, to bells and gongs for more relaxing timers.

• MUSIC INTEGRATION
Seconds allows you to match the intensity of your music to the intensity of your workout. For each interval, you can select a song, album, artist or playlist. If this is not to your taste you can simply play another music source in the background.

• SAMPLE TIMERS

Ratings and reviews

Definitely the best interval timer app. It's easy and quick to set up intervals of any kind, with the ability to nest timers inside each other to make compound timers. I have the app announce each interval with text to speech. It's flexible enough to guide me through everything from a mobility circuit to a threshold or VO2 Max workout. Very occasionally, it fails to announce an interval, but apart from that, it's a stable, reliable app, even on my old Motorola G3.

Free version is pretty much useless but the paid for app is very handy. Simply specify a time interval then write a quick line to remind yourself what you should be doing. You can create multiple time periods that will then count down one after another. Works really well for physio exercises. Good clear UI and easy to use.

I used to love this a app. I was hoping for new features and more timer variations like AMRP etc. All in One Solution 😉 I did miss an opportunity (optional) to add a workout description. Years later, there is still no backup sync like Google Drive possible. Android users are still unable to do a simple backup as Apple users can when switching phones. No new features in 2025. I downloaded this app again to see if they made any improvements, and I still don't see an easier backup option. 😒
