"Request analysis" and graph in offline mode

[zawyer1]

It would be really nice with a button to request an analysis and have a graph with blunders, mistakes and inaccuracies in offline mode for the Lichess app. This would be great for offline games played vs. the computer or over-the-board versus friends etc.

I play a lot games offline and versus friends, and there's no good way to quickly analyze the game in offline mode.

The analysis would be calculated locally, which presumably would take longer than the online analysis, but perhaps you could select the depth of the analysis beforehand?
