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.

BEFORE YOU DOWNLOAD:
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.

FEATURES:

• 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.

Good with some reservations. I bought this to replace Impetus, a great interval timer that is no longer being developed. This has a lot of the same features, but not as good. I wish it would allow me to use both text-to-speech, and an alert sound when the intervals change. If there's a way to do that, I haven't found it. Also, I upgraded to pro on my phone and then loaded the app onto my tablet. Now, it keeps prompting me to pay again.What that's about? Are there any solutions for that?

It took a while to figure out how to configure the timers, but once you do, it's fairly straightforward. It promises exactly what I was looking for in an interval timer training app. My big bug bear however is that the timer loses time, resulting in the timed segment running longer than expected. I've tried locking it, locking my homescreen, etc. The audio prompts are also hit erratic. It offers everything that I want in an interval timer, but just doesn't reliably deliver what is advertised.

If I PAID for the app, why all of a sudden can I only use 1 timer....ONE time?! You took my money and gave me nothing in return. Edit 2/8/19 Got an update for the app yesterday that I didn't bother to read, and I just figured it out. I love that I can color code all of my workouts and slide them around to make organizing them much easier. I can group them together and it was easier to find the workout that I wanted to do by color, instead of having to scroll the 50+ timers that I have.
