On both my phones, when I want to open theBrain, I often (between 20 and 50% of the time) have to click the app-icon once, wait for a brief flash and then click it again, before it lets me in.
I dislike that.

How to use TheBrain 11 fast (work in progress)

I just tried on ver .45 on a Galaxy Note 8. The app launched immediately and then selected a brain that opened immediately.

On all previous versions since .38 I've never observed the behavior you describe on my phone.  On my tablets is a completely different story.
