It really depends on where you live. A lot of places and apps are moving to require smartphones, and I hate this trend. In China for example you can't even open a bank account without a smart phone, vending machines require smartphones, and even some robotic grocery and convenience stores are requiring a QR code scan to enter the store. I even saw a public restroom once that requires a QR code scan and SMS verification to dispense toilet paper. (That's right, no shitting at that toilet for foreign business professionals without a local +86 phone number and bank account.) The whole world tends to be moving in that direction now. Uh, welcome to the future? On the US side I've had meetings with clients using Microsoft (R) (SM) (C) (TM) Teams that require a smartphone to authenticate. I have to deposit checks to my bank with a smartphone because they refuse to implement a web version and they also don't have a lot of physical branches. Even Signal, probably the only trustable E2E encryption app, wants a smartphone to log in (ugh).
