HI, I noticed I have different ratings between the app and the website. I don't know why, I logged in with the same account, I should have the same ratings, isn't ?
Try clearing your app cache. If that doesn't work it may need an app data clear as well.
I've noticed a few things.
First: the app rating fluctuates less than the website. The app goes up or down 10-14 at my rating and the website changes about 18-25.
Second: Some game modes, like chess variants, are not available on the app. So there is no rating on the app for them.
Third: The website seems to be "easier" than the app. I'm rated around 700 on the app, and games are a fair difficulty, but I went on the website and it was very easy to beat most people. I think the website just has a different player base.
Fourth: On the website, you go against people of more of a variety of ratings. You face people up to 100 above or below you instead of up to about 50. This helps find matches better, but changes how fair some games are.
I think they should just combine the games so it's "cross-platform." This would have some downsides at first, like programming, controls, UI, and variants, but I think it would be worth it in the long run.

You make some interesting observations here. What mobile Chesscom app do you run, iOS or Android?
I run the Android app, but I imagine iOS is similar.
"First: the app rating fluctuates less than the website. The app goes up or down 10-14 at my rating and the website changes about 18-25" -How much your rating fluctuates depends on your Glicko Rating Deviation (RD) score. You can read about How Ratings Work here https://support.chess.com/article/210-how-do-ratings-work-on-chess-com
"Second: Some game modes, like chess variants, are not available on the app. So there is no rating on the app for them." -Yes, the mobile apps do have their limitations.
"Third: The website seems to be "easier" than the app. I'm rated around 700 on the app, and games are a fair difficulty, but I went on the website and it was very easy to beat most people. I think the website just has a different player base." -This one got me thinking and I was intrigued by your observations. In theory there shouldn't be any difference between the user pool running on the mobile apps and the web. However, when you send out a game seek, Chesscom tries to match you with someone in your Elo Seek Range, and they try to match you with someone with similar network connection lag characteristics. I imagine most PC users are using Ethernet Network connections on the web, and most mobile app users are using WiFi or Data Carrier Network connections. This could result in two different user pools of users between the web and the app.
"Fourth: On the website, you go against people of more of a variety of ratings. You face people up to 100 above or below you instead of up to about 50. This helps find matches better, but changes how fair some games are." -This shouldn't be, make sure you are setting your game seek Elo rating ranges the same on both the moble app and the web.
Those explanations make a lot of sense. I agree with you, and I ran into how the glicko rating system works while researching something else yesterday. But I've run into another problem: the rating isn't syncing properly. When I got back into using the website, I climbed over a hundred, and am now 829. On the app, though, I'm still 719. Is it supposed to be different or is this a bug? I'm pretty sure when I started using the website again it was the same. I'm gonna check now.
Edit: I was 690-something on the website before the climb. It wasn't synced. I still don't know if it is supposed to or not.
Also, I'm on android.

The app pills data from and pushed to the site. It's possible that the app is either lagging pulling updates or has bad cached data.

Your Elo should be the same on the app and on the web.
Are you sure you are using the same exact account to logon to the web and the Android app? You didn't accidentally create two different accounts like YeeterDeleter01 vs YeeterDeleter001?
Is the Elo differences the only differences you are seeing? Is your Profile PIcture the same? How about Join Date differences, number of games played, dates of when games were played? Can you make screenshots of the app and the web that show the Elo differences?
I noticed the same thing regarding Elo changes on the app (ios) vs online play. I typically play on the app and see moderate changes when I win or lose (say 8 to 15 Elo). Went online yesterday and am getting huge changes (65 to 100). Going to start playing online more!

Your rating changes look normal for your games, with no large changes in ratings.
