We are on Version 6 of our prototype testing already! The feedback so far is giving us fantastic direction and navigational insights. Already drafting V7.1 as I type this (V7 has just been done in Flinto which we are moving away from in favour of Invision App). Two gifs of V6.0 is shown below with an android interface but V7.1 will be an iOS interface as further to development tools and supports open to us, our team have decided to focus solely on an iOS app for release late next year. Loads to do yet so back to the drawing board as it were!
