In some ways I think this is the environment Apple has cultivated (maybe not deliberately) over the years. Basic features like cut & paste are left out, and then announced in a later version to as though it's this great innovation. Not that this particular app is such a basic feature, but illustrates the reasons why there are so many single-function utility apps. And of course the danger of them for their developers, if they rely on them for their livelihood, is that Apple will at any moment swoop in and copy the most popular ones. For the record, I'm not sure there's anything wrong with that on its own, but there is when Apple doesn't let developers access iOS as deeply as they do themselves.
