A new class of activity-tracking apps that have recently had significant success on Google Play, the official software store for Android, has been downloaded onto more than 20 million devices. The apps present themselves as a pedometer, fitness, and habit-building tools, promising to award users randomly for maintaining an active lifestyle, achieving distance targets, etc.
But, according to a report by the Dr. Web antivirus, the prizes could be difficult to redeem or are only partially made accessible after requiring users to watch a lot of advertising.
