As far as fitness apps go, RunKeeper is now considered an oldie but a goldie; the free version tracks exercise, maps out runs and gives information on distance, calorie burn and pace.
But if you want a gentle nudge towards keeping active, Breeze from the makers of RunKeeper is the ticket.
It uses the iOS motion sensor to track steps as you walk about during the day, delivering personalised goals based on previous activity.
Notifications offer suggestions and encouragement. The idea is to build gradually towards a more active lifestyle. It’s iPhone 5 compatible only but try Moves for an Android equivalent. breezeapp.com
