the Fitbit mobile app
Just Desserts progressively reveals images of foods that contain as many calories as you've burnt so far today. Exercise more to see the best foods!
If you touch the bottom left corner of the screen, the current activity measure will cycle between energy, steps, distance, active minutes and heart rate.
If you touch elsewhere, the images will briefly change to correspond with the amount of energy you SHOULD HAVE burnt by now, so you know whether you're on schedule or not. The activity measure will also change to show percent above/below the expected value.
Just Desserts is customisable. You can upload up to five of your own images so you can see your personal favourite foods revealed as you burn calories. You can show or hide seconds, change the date format, vary the number of tiles, show or hide the tile grid, and even display energy in kJ.
Of course, you shouldn't always eat what you see! A healthy diet is preferable to a pizza every day.
