Making apps deliberately stupid will earn 1 star every time.
Apple could so easily make this app decent, but, as with all of their apps, they intentionally exclude critical features, such as a means of organizing files (one folder level is not enough) and the lack of Dropbox (or similar) integration, thus making the app all but useless.
If they didnt make their own cloud service so flakey and hard to manage, the lack of Dropbox integration wouldnt be so bad...
Apple should look around at apps that have high reviews and take notes. Not that that would help since Apple already knows how to make all of their apps great, they just choose not to...
For each Apple app, the problems that result in bad reviews come from choices that are deliberately stupid.
