Wanted - mobile chess app/site that can view a pgn as a "tree" of possibilities

By a tree I mean a visual list of moves and their probabilities to the side of the board.

I've put together a pgn of all opening lines I want to play and want to learn/view it on mobile when I'm commuting.

The problem is that all apps I've tried so far either (1) have no functionality to view the "tree" of moves (like you can on Scid or chessbase on PC), or (2) have a viewable tree but you can't import custom pgns.

Does anything fit the bill for this?

DroidFish maybe?

Just downloaded it. Theres no tree unfortunately.

I'm looking for the same kind of app, I downloaded Scid on the go, thinking that it will has it, but it doesn't. Good app for browsing databases though.

As far as I know only Chessbase online Android app has this feature:

but you have to pay for it...

I use pgnmaster for android. It shows opening book, but it's not that big. PGNmaster is not free, but it's way better than scidonthego, droidfish, etc.
