Either a release of TheBrain for iOS is imminent or this YouTube video on TheBrain channel is a premature mistake.
Users of TheBrain (Previously Personal Brain) like me have been clamouring for a few years now to get The Brain released on iOS. There is a forum for TheBrain iOS Beta (currently protected and limited) but no updates on the website.
This exciting news is a long time coming and with any luck a release is imminent. The interface appears clean and sensible and the demo is on a non-current iPad so already it gets a couple of ticks.
In case it was a mistake, here are some screenshots from the video.
