I do agree that chargers requiring an app are a royal pain. We're an all-EV household and I don't bother with local chargers that don't have readers or support plug-and-charge. There's a lot of Shell chargers in our area that require an app to work and almost no-one uses them because of how clunky it is.
For all of those people, using the chargers won't require downloading some new clunky app that they only have because of EV charging.
It will be that an app they already have and use regularly and already have their payment information adds EV charging to the list of Walmart goods and services that they already use it for.

Teslas do not need any app for charging. I mean sure, they do have an app, but no need to even have the app on the phone or with you to charge. No need for a phone or a credit card or a code or a password or a chip or a retina scan or interacting with a screen or tapping a keypad or anything. Just plug the plug into the car at the supercharger and it charges. Or, do it at home, cheaper.
