I went to a great event last night hosted by the Social Media Forum in London. The guest was
@georgeberkowski, author of the book “How to build a billion dollar app”. The key message for me that came from the event was to build an MVP (Minimum Value Product) app as quickly as possible then test it with at least 500 users to see if you are on the right track. The feedback from the users will soon let you know how good (or bad) your app is!
