Chess apps that provide a 3D view of the board and allow export of PGN I'm looking for an Android chess app that satisfies the following criteria:


Provides a 3D view of the board and the pieces (required) 
Allows one to have an account, and invite friends to play matches online (required)
Allows export of PGN (optional)


Could someone suggest such an app?
Chess.com is probably one of the world's most popular online chess platforms. It has an app and a website (which offers many more features, such as a beta 3D view). In both, you can export game PGNs and have an efficient friends system in which you can challenge people to play. There are also many other beneficial features- free lessons from master players, tactics training, vision training and numerous drills to improve endgame play, as well as Stockfish analysis. Hope this answers your question.
