I would love to give the app 5 stars, but it missed features that are easy to add and would make it rock. Specifically, the alert system is too rigid. I want to use it for speed bag and heavy bag exercise and having text to speech is great, but I cannot also define a gong or some other distinct sound to mark the end of the exercise. Having the alerts as check boxes instead of radio would be great, it would also reduce the size of this menu, since the combinations will be up to user, not the developers. Once done, it gets 5 stars from me.
