I read a questionable, uncited source on Reddit (I know...) earlier today where a posted was complaining that some large banking application inside of Canada did not support feature parity between their mobile application and their desktop web application. The top upvoted comment seemed to insinuate that "why do you care? the app is more secure"

Scouring the web for claims, you mostly get garbage listicles with almost no substance.

So HN, any experience with them when building or using products? Intuitively, as a blanket statement this seems absurd without knowing the details of the application because it's very easy to build an insecure application... if you want.

Have we met any of these in the wild? Bank applications seemed like a prime candidate because many of them have very old backends and I wouldn't be surprised to learn about hacks that some of them have layered atop to build their mobile apps :)
