GUI and Ini combo for Android?

[Blackbirdx61]

I know Arts GUI will run UCI engines but without the Polyglot support that makes UCI basically meaningless.

Is there any GUI engine combination out there that allows the player to control parameters via an .ini file.
Most specifically ELO, and Book used.

I have Droid fish, and you can set the % Strength on the Stockfish and CooCoo Engines by Percentile; but what the Elo's of those Percentiles. are
I have no clue. I have a nice Winboard set up on my home computer now, but I find; just given my circumstance I am playing 90% or more of the games.
I have the chance to play on my Tablet.

Any Devs out there - This seems to me to be a rather neglected space. BB.
