When the app was pitched on Dragons' Den, the dragons said they saw its potential and how it could potentially be incorporated into other services provided by companies like Google. Mr Sansome said: "I had offers from five dragons which has only happened a few times in 22 years of Dragons' Den. "The filming took place a year-and-a-half ago and keeping it a secret for so long has been absolutely killing me. "Sara Davies' team have been absolutely fantastic helping with account PR and he has found the business consultants very helpful. "We had tens of thousands of downloads in the first 24 hours after the show went out. "But it has also been a humbling experience as we have had emails saying 'thank you so much for creating the app. I have got a stoma bag and need to go to the toilet on a regular basis and this is going to really change my life.' "The idea now is to expand it. We have been working with Transport for London to make accessible tube map and we want to put a live feed in there for people going round London - and we want to do our own chatbot as well."
