Needs some tweaks, but is good

I just got this and it is a good workout. But I can see it getting boring quickly. For the price it was worth it.
There needs to bee a few tweaks though. Between exercises there should be an audible alert. When working out you are not watching the screen to count down the time or read the ready, set and go. I found myself continuing one exercise into the next and having to try and figure out what new movement to start while the timer was already going.
When the workout is complete the app needs to release the processor. I found that if I dont click on the home button the CPU is continually being used and the screen will not turn off.
