Easy to use interval training timer with six presets.
Use it for your gym sessions, training at home, HIIT, isometric exercises or any other type of time based training.
The app is built with buttons, big enough to be used with tired fingers or when buttons seem really small. All presets can be loaded on the main screen, so you don't have to change screens between exercises.

■ Customize six presets
■ Modify activity time, rest time and number of sets for each preset
■ Four sound sets included
■ Even works when the app is in the background!
■ Listen to music during training with any other app
■ Start and Pause by tapping the time or buttons
■ Fast-forward rest interval
■ up to 32 sets with 5 sec steps for times under 2 mins, 10 sec steps over 2 mins and 1 min steps over 8 mins (more than 32 won't work in background due to iOS restrictions)
■ Use the volume buttons to set the signal sound volume

This App Is Wonderful

This app is just what I was looking for. I love the presets! My only complaint is that it works on my iPad but the sounds don't work as they do on my iPhone.

Simple. Perfect.

I recently read the article in the New York Times about the successful research into shorter but intense interval training as a substitute for 30 minutes of moderate exercise. That led me to search for an app like this. What a find! It has just what you need and no more. As a UX designer I really appreciate how straightforward it is to set and use the presets. The audio prompts to let you know when an interval is ending play on top of whatever music you're playing (and indeed fade down your music a touch to make sure you hear them - then fade it back up). The only small suggestion I would make for the next rev is to have the sets and overall timer count down, rather than counting up to be psychologically consistent with the interval timer (ie "Sets To Go", "Time Remaining"). Thanks for creating something so clear and functional.

Simple timer that gets the job done

I do lots of isometrics. I have a timer for most of them but needed something to time various exercises I do irregularly. I wanted something that ticks off the seconds using sound and something easy to set up with a number of timers. This meets those requirements.

What I don't like, however, is that I need to set exercises for 7 seconds. I can't do that with this timer. You have to go from five to ten, etc. I really find that restrictive and don't like it.

You can set up the number of sets, intervals and rest. I'd like to be able to set up sets and reps as well.

Also, in isometrics, you need so much time for the contraction and another 3,4 seconds to inhale and get out of the contraction before you go into the rest. You can't set it up like that. So, you have to set it up to allow for all the time in the work part and guess somewhat when doing the contractions.

But otherwise I find this a very good interval timer. It's simple and basic and the fact it is audible in both the work and rest makes it somewhat unique and very helpful.

If the developer would fix it so I could set it in minutes such as 1,2,3,4,5, etc I would likely give it 5 stars.

I tried several and bought one. I very much like the other one I bought but it only allows 3 timers. This is an excellent timer.
