Funny you should mention a banking app. The ING banking app on Android is dreadful! It is mostly because it doesn't adhere to any of the standard Android conventions such as a toolbar, sliding left-hand drawer for jumping to different sections, the "back stack" is well handled, etc. It makes moving around a pain. You can't easily jump between your accounts or cards, pressing back after viewing your balance takes you right back to the start, and so on. Another bit of anecdata is the Android ebay app. It used to be an OK not-really-material app, probably iterated on since the Gingerbread days, then Holoiefied. Then about a year ago they updated it to be (I think) more iPhone-like and the fans really hammered it in the Play store. Lots of "what the hell have you done, 1-star" type reviews. I didn't like it much either. The problem was again that navigation was weird and non-standard. Everything was light-grey on white too, which didn't help. Then they updated it again fairly recently to be what you might call a prototypical Android Material-design app, and it really was a relief to see. Now it works great, there are far fewer weird mystery navigation parts and the reviews are picking up. I get what you mean, that apps can add things outside the norm, but they really need to get the base layout right. If you have a few odd/power features, that's great, but don't make the whole app some weird Homer's Car-style monstrosity.
