Light Up converts the combined activity of you and your friends and family into virtual electrical power, which is then measured to see how much light your accumulated steps would generate. If you’ve spent more time sitting on the sofa than you have striding along the street, you’re likely to light up little more than a tiny LED or a torch.
On the other hand, if you’ve been taking great steps to get out and about, you might find that your activity levels are suitably high to power a set of floodlights or even an entire city! When you get to this stage, you know your willingness to walk has come on leaps and bounds.
