While a recipe isn't protected by copyright in the US (and many other countries, including the UK), the wording of the recipe could well be an original literary work, the layout of the page could attract a copyright (as it does in cookbooks) and you're right that the images would be protected.
All that said, if the import is being used for personal use only and not being edited, then it's little different to printing it out and putting it in a binder. I don't know much about US fair-use laws, but in the UK it would seem that reproducing a recipe in an app for your own use would qualify as fair dealing thanks to being personal study.
That only applies if the imports are specific to the person importing them, of course. If they're shared or published, then it's a different story. Also, if you're importing more than one recipe, so it's a significant amount of the published work, then that'd be an issue too. You can't import a whole cookbook and claim it's personal study, but one recipe out of dozens is probably fine.
