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.

Was required to purchase and use this app for work purposes, has mostly worked fine for over a year. Extremely disappointed to learn that it has no support for Galaxy watches as I just bought one to use so I don't have to hold my phone to see the timer. Very obvious that Android version is lacking in features and updates compared to the Apple version.

love this app. it really is like a personal coach. only thing I would like more would be if I could program seconds app routine to prompt me to start it based on GPS and or other place based prompts like nft tag nearby or blue tooth activation or even a phone call start or end in general an sms from a person and or time of month day week or year. also would love to have Playlist options like random play list and straight play through play list vs simple play through one mp3 and also volume.

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.
