I am more annoyed that banking apps don't have an option to show different views based on pin number. For instance if you are in controlling relationship, partner might ask you to show your bank account to see what you spent money on. That suitcase and storage unit you rented to plan your escape? It's in plain sight and so the beating that follows.
And that is just one angle.
Phones themselves should allow for shadow user accounts, where you log in to completely isolated, encrypted and different environment based on pin number, so you always have plausible deniability.
