That’s often the case, but the other common problem is lack of consideration about hierarchy. It’s fine if every function of the app isn’t accessible with a single tap — that’s probably not necessary except for the app’s most pivotal functions, but most things should be able to be used within two taps and almost everything within three, with the paths being logical and predictable.

It’s plenty doable, but like I said it takes some sitting down and planning and perhaps more importantly, design centered around the user and their needs and less around looking pretty in a slideshow or trying herd the user around.
