If that idea doesn't work, then I'd punt. (You could name the engine 'Stockfish Chess960', or something similar.) Then try analyzing a Chess960 game using the Stockfish engine. For example, you could install the Stockfish engine into the Fritz GUI as a UCI engine, making sure that you select the 'UCI_Chess960' parameter during installation. If there isn't a Chess960 parameter for the Fritz 13 engine, then my next step would be to find a free UCI engine that has Chess960 capability (like recent Stockfish, Critter, and Spike engines). If you prefer a longer game, where you get more time to analyze. From there, you can select your own time limit, or choose from one of the presets the Defaults. If you want to play a fast game, click on the Blitz Game button. If there is, then enable that parameter and then try to analyze a Chess960 game with that engine. To set the Time Control in this version of Fritz Chess, you need to select the Home menu tab. I'm not sure of the exact steps, but you'd have to go into the Engine menu and look at the engine parameters for the Fritz 13 engine to see if there's a setting for Chess960 mode. If the Fritz GUI isn't set up to specifically analyze in Chess960 mode (and I didn't see anything in the Fritz 13 manual that would indicate that capability), I'd first see if the Fritz 13 engine has an engine parameter for Chess960 mode. An optional 'move coach' highlights valid user moves during input and last played engine move.

The application accepts moves through the touch screen, trackball, or keyboard (e2e4 pushes the king pawn, e1g1 castles king side, etc.). First of all, I don't have Fritz 13, and I don't have the answer to your question. Chess for Android consists of a chess engine and a GUI.
