I pity you if you receive an .hwp file from someone living in South Korea. Look at the list of formats this jack of all trades, master of none app attempts to handle. This would be impressive, except its impossible to do something as simple as copy text.
This app is completely useless and its desktop counterpart is as well with terrible non anti-aliased font rendering, poorly resized images with messed up aspect ratios which make most documents look extremely unprofessional.
Of course, this program also completely ignored a central tenet of iOSs design philosophy, which is to hide the file system from the user.
I would go on, but let me leave you with a plea:
Dont buy anything from Haansoft. If someone sends you an hwp file, demand that they resend it to you in a more open and editable format, even Microsofts .doc and .docx format are better and that is a sad line to end this review with.
