I signed up at 19.50 USD to give it a trial as I wanted to lose 3 kg over 1 month which as per advertising its easily to achieve. After that I got another automated deduction of 29.96 USD and 59.98 ( through paypal without authorisation. I tried to get the refund through their customer services which seems to be impossible. "BE AWARE" this is a scam. I totally regret this purchase, also be aware if you purchase it though the website you cannot cancel it through the App, the App also does not appear on the "subscriptions"on you iPhone.
