I would really like an app on my phone that can beep at me at different time intervals. For example I am using a training program at the moment where I do a n exercise for 50 seconds and then rest for 10 and move straight onto the next one. This is very difficult to time using a stop watch on the phone and I can always look away whilst donig the excersise. I want something that I can hear.
Does anyone know of an app that would be suitable?

Thanks guys.
