Lost 20lbs but nothing special

Great for a free app, they just need have different tones one for starting a workout and one for starting a rest phase

If you want to work out this app is basic and keeps you moving! Do expect it to tell you what to do that part is on you! Try jogging, speed it up, jumping jacks, air squats, split jumps, push ups, bear crawls, plank. Repeat! Boom now you can't complain about this app! It's free people! Come on get moving!!

its a timer only and it asks you to download a hotel app for a free upgrade which appears to do nothing, not evdn removing the offer for the free upgrade.

Have no idea what the difference is between the original app and the "pro" app (I tried both) but this app says you have to download a Hotel app in order to upgrade. I saw no difference between the free app and the pro app. When you download the hotel app, it wants to take you to a website rather than opening up an app. I may be overly skeptical but this app may be earning some revenue from the "clicks" but my main concern is that we are directed to a website rather than the app working independently.

Good excelente

Gets it done

Real interval training on the go! Buzzes every sets and rests. Sets on your control.

Great little app. Very easy to set the time you want for your exercise and rest intervals.

But the graphics need to be updated to take advantage of the iPhone 5.
