I have never tried or experienced downloading a casino on my mobile device because, as far as I know, the risk is quite high.
I am more comfortable gambling on crypto on the casino website itself, not on those that are only downloaded from the Google Play Store.
Because almost most of the casinos that have had issues have always come from downloadable casino apps on mobile devices promoted by social media influencers,
If the casino itself has its own game app in either the Play Store or App Store, one can still use it that way, or they also announce the official link to the casino app on their website, at least one can rest assured that it's their trusted casino app and not any clone has been added to the Play Store or anywhere one can download the application from.
Using an app for betting that is mobile-friendly is one of the best, as it saves you the stress of logging in whenever you want to play a game, as the website can log you out depending on how secure the casino is.
But for the one the OP dropped, one needs to be careful as you can't trust the source, and what is the limit to the capability of the app aside from deposit safety? What else will the app have access to on your device?
