The information is useful, but appears to be pulled from third party websites so you could probably find all this info yourself online. The game has constant, annoying ads that pop up every minute or so. Some of the ads are videos with loud audio that cannot be dismissed, despite the X button at the top of the screen. So you have to watch the whole video and then wait for the ad to disappear.
