Good Reader was one of the first apps I owned back when we got our first iPad. Their developers continue to innovate, allowing Good Reader to retain its status as the best file manager even after all these years!
Good Reader is always one of a few must have apps I put on each and every ios device I or any family member uses. We dont use it a lot as some do, because you can use it for virtually everything, but we have it available to use for when we need too.
Our primary usage is as a iCloud Drive repository for all of our important documents. We have perhaps 20 folders with a couple hundred files ranging from images, PDFs, Pages & Word document. But you can also keep other types of documents such as rich text too. Rarely do I encounter a data type that doesnt work in Good Reader.
