Most EVgo charging experiences have been plug and charge. I did have one experience a while ago that needed an app but that was one of their older chargers which even still had their old logo on it. All their newer chargers have successfully done plug and charge.
I've had tap to pay work with Google Wallet at Road Ranger (Freewire) and Francis Energy chargers.

That's why I included the language "as well". I've used a number of different brands of EV chargers.
Out of all the times I've used a public DCFC, I had to use an app maybe 10% of the time. And of that, it was only earlier into my ownership, I haven't had to use an app in about a year. Every charger I've used in the last year has been either plug and charge or supported credit cards directly.

Other stations require payment, but EVGo plug and charge works too if you’ve set it up ahead of time.
This has been 100% of my Electrify America experiences as well, along with a few other brands. Some have been able to take payment by tap to pay credit card as well without an app.
