On the iPhone app, I can see my past games in "Play" - it's got all of my current games at the top, but scrolling down there are my "Completed Games" below.
Clicking on one of those brings up the gamea and the result in a dialog box; choose "Analysis" instead of "Share" and then on "Self Analysis", you get the end point of the game. I'm not sure if there's a quick way to jump to the start, but you can hold down the back arrow and it will zip through the game in reverse to the start, and then you can step forward through it.
There may be an easier way to do this in the app, but generally if I'm going to analyse a game of mine, I'll use a web browser on a PC.
I want to go back and analyse it. I can only use the site on my mobile or the app right now. I already found it on the game archive but I wasn't able to view the game itself, i.e. the moves. Thanks
