It's a good idea to bring this up.

It is really easy to get lulled into a false sense of security.  Hey, it is on the official app store,  must be safe, right??         I don't use mobile wallets, but if you do - just go straight to the source,  make it a secondary wallet and only put the crypto you intend to use for that day on it.       That's the only way to minimize your risk.
