There are several converters in the app store. I chose this one because it doesn’t just open the files, it 1. Converts them directly to .doc files, and 2. *with no loss of formatting.* None of the other converters I saw do either of these things. I am a college writing instructor, and I do a lot of work online. Students submit files that I later open and print. No matter what I say about Save As and submitting .doc or .rtf, there are always some .wps files. Nothing on earth opened .wps files. Running after students to convert their files is a pain. Now I can just convert them myself!
