I just released a new app 7 Minute Workouts. The reasons for creating this are similiar to my reasons for Steps+.

In addition to these things I was tired of being asked to upgrade and nickeled and dimed for seperate workouts and buying 'everything' but that doesn't include all workouts. Not chill. And you can't *really* customize in most of these apps.
Mine is 100% free and fully customizable. Download it and let me know what you think!!!
