5 stars: The check in feature is really nice to get daily free goodies. The map feature is awesome as well if you need help in finding chests, ingredients, and the different important items scattered around the map to offer the trees/statues. And the Battle Chronicle is really useful to see when you've regenerated the currencies and finished expeditions without going into the game. Very useful!
5 stars: The bug has been fixed in the new update now, i can log in again, thank you :D (Previous review: I have this app for almost a year now and recently I suddenly got logged out from my account, and when i tried to log in it keeps saying 'system error' and won't let me in.)
4 stars: Pretty well contructed app, perfect for sharing and communicating with the rest of the community. Not only that its super cool we can access and share some of our game data with other users. My only issue is that the tools are no longer showing up like the check-in and teyvat interactive map.
4 stars: It's great, but sometimes the notifications I get I can't even tap to see where I need to go, it says 'deeplink not supported'. So that's always anouinh that I have to search through all of the app to see where it is. Otherwise tho, it's great. I love being able to use it to see other people's fan art, what they think about characters, and their memes for the game.
3 stars: I liked how it connected to my account until I realize that doesn't matter for tracking what I've explore on the map....
