HealthTap is a free app that allows users to contact doctors with symptoms and queries about their health. Launched in 2011 the application has over 100 million users and 60,000 participating doctors. Founder Ron Gutman plans to expand on the currently free service and offer a premium edition which would allow users to have video consults with doctors, receive prescriptions, provide checklists and more.

Priced at around $99 a month, the subscription service would also give regular health updates and work in a three module framework: learn, get help and take action. Does this spell the end for face to face doctor-patient consultations or will it struggle to take off? What do you think?
