Especially in the corona-virus crisis it will prove interesting whether some mandated "contact tracing" or "vaccination pass" style Apps are going to effectively turn into an Android/iOS Smartphone requirement for everyday life.
In Germany it's e.g. already impossible to use the DHL parcel receival stations without Android/iOS. Loss of some ticket options for public transport also seems to be on the horizon. Also forget about car- and bike-sharing.
Also some banks try to force you to install their own proprietary TFA app for online payment (even if you just use your credit card in an online shop).
