I need an app built for IOS, Droid, and Windows that is a timer for an exercise routine. The routine is for a book that shows some specific exercises. The app supports the book and shows the exercises that they need to do along with a timer. The timer is 20 seconds on and then 20 seconds off. When the time is about to be on, there needs to be some beep to notify the person that it is time to exercise again. The pictures below show an app with similar features called the 7 minute workout. It is a simple app that can have features added later.
