About this app

Seconds is widely recognised as the best interval timer for HIIT & Tabata training for mobile devices and is recommended by celebrity trainers and personal trainers to their clients all around the globe.

Non-paying users may create as many timers as they wish, but once an interval timer is started it may not be used again. Upgrading to the full version removes this restriction.


• Large, full screen, color coded display that is easy to read from a distance. The display works in either landscape or portrait.

• Templates for HIIT, Tabata and circuit training. A custom template to create every interval. And the compound editor where you can combine many interval timers into one.

• Speaks your interval names so that you can follow a workout without seeing the screen at all. Seconds can even provide prior warning of the upcoming interval. Other alerts including beeps and bells are available.

• Coordinate your music with your Tabata workout. Each interval can have its own music assigned allowing you to match the intensity of your music to the intensity of your HIIT workout.

• Seconds runs in the background allowing you to either have your display off, or use other apps while the HIIT timer is active.

• Export and import. Share the Tabata timers with friends or download them from the web and install them in Seconds.

Works as advertised. Can set multiple countdowns, intervals, etc. I use this for workout set breaks (45 seconds) for walking/jogging intervals (2 mins walking, 45 seconds jogging), and battle ropes (45 seconds on, 15 seconds rest, for 8 sets). Timer speaks over music and anything else on the phone to state midpoint, and 3 second countdown to next internal. Colors can be customized and counter can be set to full screen. I use it for every workout.

I continue to use this app because it's indispensable but for the years I've used it, it has persistently suffered from the same issues. Namely: stuttering countdown (how did an app named Seconds manage to not even measure a second accurately?) and frequent app crashes on longer timers or when timers are running in the background. These issues have prevented me from springing for the paid version.

I hope future upgrades will include a log of workouts I've completed. March 2023 I love this app. Makes working out a breeze to track. Keep up the good work. I have a new ask: At times I want to change the interval of individual time segments (think HIIT) but I have manually change each segment. Can you upgrade that this change is only done in one place--like we do for rest periods in a circuit timer. Please and thank you.
