chess.com app says one thing, chess.com website says another, about the same game!

Hello. 

Just a little confused. I have been putting stock into the reports that the computer analysis produces after my games. But recently I played a game where, on my phone, a particular move was noticed as "best", and when looking at it again on my laptop, the same move in the same game was called an inaccuracy. The overall accuracy on my phone was also 7% higher than the website. 

How seriously should I be taking these game analyses?

Please provide copies of the relevant analyses so that someone may help you reckon the truth.

Sure, I'll do it tomorrow, I am passing out---but my concern is less about the analysis of that one particular game, and more about how to view/use the chess engines moving forward and how much to trust what they're saying. It's just odd, because I thought they were the same ones.

Naturally, the accuracy of the analysis depends on the computing power that's put into it.

Were your phone app and the website (accessed by computer) both analyzing the game to the same depth? If one was looking 16 ply into the position, while the other was analyzing to a depth of 22 ply, then of course the verdict would be different.

You are not crazy.  Evaluating from a phone vs on your computer vs on the chess.com servers will yield different results here.  That is unfortunate, but the engine analysis here is not prioritized at providing consistent results across platforms, especially for free members.

Do not put too much trust into what any engine labels as the single best or an inaccurate move.  Especially, do not put trust into what you see from an engine without understanding the depth to which it was calculated.

Look at the top choices from the engine.  Evaluate what makes sense to you, and what you could reasonably expect to have seen.

What can you learn from the patterns that the engine is suggesting that are better than the moves you played?  What actionable step can you take the the engine lines to improve your next game?

I appreciate the feedback from everyone. Thank you. I have a better picture now. Cheers!

I think you cannot change the depth on the phone app, only on the web, or I am not seeing where this setting is located.
