Considering there is no free trial and you have to pay £20.99 immediately, it doesn't do anything special at all. I thought it would calculate a bespoke plan for me, considering I had to give it all my details. Its just false advertising. I linked it to my FitBit and it doesn't even count my steps or sync properly, its saying I've done way more than my FitBit says I've done. I even paid the extra money for the downloads whi, to be honest, give me no extra input at all. Don't waste your money.
