Documents by Readdle is one of those apps that no iOS owner should be without. Here is a few of the things it can do:
- Sync Dropbox, Google Drive, Skydrive, FTP folders locally (it supports other services as well)
- Zip and unzip files
- View and edit PDFs and text files
- Play media files (including remembering playback position on .m4b audiobooks)
- Connect and upload files to FTP servers
I had typically used GoodReader for these tasks before, but Documents is just as capable and is a lot nicer to look at. The only complaint I have is that it is a free app. I read that they may offer IAP upgrades in the future, so I hope I get the option to support the development. Readdle also makes the great Scanner Pro, PDF Expert, and Calendars 5. I highly recommend that you download Documents for iPhone and iPad.
