About this app

LOOK NO FURTHER, Seconds Pro Interval Timer is the most advanced interval training timer available for mobile. Seconds has been downloaded over 2 million times, and has over 7000 5-star reviews. Other interval timers don't even come close when it comes to quality, features and ease of use.


• Large clear timer display
• Templates for HIIT, Tabata, Circuit Training and more
• Custom timers to create any intervals imaginable
• Speaks your interval names
• Loud or soothing alerts
• Coordinate music with intervals
• Share or import timers
• Runs in the background


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.

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.

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.

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.

Share the interval timers you’ve created with your friends either via our companion website ( or via email attachment

Seconds comes with a host of pre-made timers in the timer repository.

Fantastic app. Totally customizable or use the pre-made routines. Can be used for any exercise routine that needs a timer. Voice on reads your next exercise. Voice off you read yourself. Alarm on or off. Customize each exercise with a color of choice. I do HIIT and use a different color for each kind so from a distance I can see what type of exercise is coming next. Every exercise can be set individually with time, color, etc. Different routines for each day of week can be created as well.

I do not use it for sports and exercise but as a productivity app. If I need to allot a specific amount of time to work on something before moving on to my next commitment this helps me stop on time eliminating the risk of falling into hyperfocus and continuing to work. I use the option to have a halfway beep to help keep me aware of the passage of time. It is also perfect for anybody who uses the pomoduro technique - use the custom timer settings to specify work and break intervals.

This app has kept me on track with my workouts! I can workout anywhere and anytime as long as I have my phone. Several varieties of workouts can be programmed into Seconds Pro, along with customized sets and set lengths, rest times, and even custom colors! The voice announces what's next and counts down the last few seconds at the end of each set. I haven't even explored all the features, but nonetheless I love this app!
