Are health apps really beneficial?

Health apps can sometimes turn out to be pretty weird as they tell you to walk 10,000 steps a day could be harmful for some people,an expert claims.

Dr.Greg Hager,professor of computer science at Johns Hopkins University,said many fitness trackers have no real evidence to support their targets.

He told the American Association for the Advancement of  Science in Boston,that the figure was based  on a 1960 study of Japanese men who were estimated to burn 3,300 calories by walking 10,000 steps.

“But is that right the right  number for any  of you in this room “,he asked.”Who knows”.Hager added,”Untill we have Evidence based apps you could amplifyissues.I am sure these apps are causing problems.”
