Gross from Forest Giant is one of a growing number of apps that take advantage of the M7 motion co-processor in the iPhone 5s. The app sets itself apart by breaking down your movement into categories and displaying it in a simple and clear way that is easy to understand.
Gross uses a text-based interface to present your motion data to you. The main screen of the app is a list of the days of the week. Under each day is blue line that represents your overall motion. At the bottom is your gross movement that summarizes your movement for the past seven days. The app focuses on the here and now, so there is no fitness history, just your performance over the past week.
Tapping on a day of the week brings up the motion data recorded for that day and breaks it down into degree of activity. In a quick glance, you can see how much time you have spent walking, running or cruising. You can also see your gross stats for the day. On the right side of the detailed view, there is a column that shows your activity throughout the course of a day and allows you to quickly determine the hours of the day that you are most active.
Gross' strength is its simplicity -- you don't have to wade through charts and analysis to get to your core motion data. It's a basic tracker that displays your movement in an easy-to-access and straightforward way. It's perfect for those who don' t need the extra fluff and just want to see how much they move during any given day of the week.
Gross is available for free from the iOS App Store.
