Counts and displays calorie expenditure.

The Polar OwnCal feature shows your energy expenditure during one exercise session as well as your accumulated kilocalories during several exercise sessions.

You can set daily and weekly exercise goals in terms of calorie expenditure with the OwnCal feature. Because the OwnCal tracks both the energy expenditure during one exercise session and the accumulated kilocalories during a longer time e.g. one week, it helps in achieving both short term and long term goals.
