Chess.com premium membership?

Do we still need premium membership if the go to idea is that you can analyse via the Chessup app?

I noticed that in the chess-com app, the accuracy of the games were updated, without having premium. Do I make sense, is that logical?

The ChessUp app and analysis is free and unlimited. Chess.com has a limit on number of game reviews per day, but self analysis is unlimited I believe.

In terms of what generates the accuracy score - I am not sure if that is always indicative of game review available or not.
