Many Android phones have some kind of password-protected separate space where you can hide files and apps. So if you want an app for a second punting number, like Hushed, or a punting-dedicated browser, you can put them there, and no one accessing the phone will see them - you will have to access the password-protected space and only then will you see your hidden apps and files.
Samsung calls it "secure folder", Realme "private system", Huawei "private space", Oneplus "hidden apps", etc.
Is there anything similar for iphones?
How do iphone punters handle these apps?
