The Back App is not a household name yet - although I am confident it will become well known as more people realise how well it can help with a bad back and be very good for your posture.
I recently had a drunk ask me if the Back App I was carrying was made in Sweden and thought my message was getting through to some members of the population at least! Today in Clerkenwell I was leaving a customer carrying a Back App and I was stopped by someone asking if 'That was my Back App or was I selling them?' It turned out that the gentleman worked for one of the retailers of the Back App - he put in an order there and then and I delivered the chair later the same day.
So while Back App is not a household name yet I have been stopped in the street by people to order them!
