To be fair, the app may be developed by a completely different team.

If your argument is still that you don't want to trust a company that can't make both functional, well... maybe you shouldn't be going to Jack-In-The-Box in the first place.

My point is that I'm not going to give app-level access to my phone to a company that doesn't care enough to have a functional website. That said, I'm unlikely to install an app for anything on my device.

I don't actually install that many apps, and generally not retail apps anyway.

I looked inside an average proprietary authenticator mobile app with 2 button interface and can confirm it's dumpster fire with 26mb of compiled code.
