1. Sometimes it will be paid $1 when you download it
- But it won’t be paid it actually, it’s just the process to check the valid of registered Credit card on Appstore.
- ThinkfreeOffice viewer edition for iPhone is free of charge.
2. When the program does not work well
- You should use the program after setting the [setting-resetting] option to “basic setting” when an error suddenly occurs.
- You should use the program after finishing the program by double clicking the process.
- If you cannot open the document because of the text encoding, you can open it by setting the [setting-viewing the text document-text endcoding] options. (You can open the document by setting “CP949” when it is written on Windows).

■ Matters that require attention
1. Some characters may not be displayed correctly except Korean or English characters because ThinkfreeOffice viewer uses the font developed for mobile device.
2. Font types of the original document could be changed to the mobile font type. And the layout of the document could be changed as well.
3. It does not support OLE object, Chart, Form Controls, sound/video/flash and image files(AI, CDR, CGM, DRW, DXF, EMF, EPS, HDR, HPGL, PIC, PICT, PLT, WPG etc.) included in Hangul document and image effect as well.
But if you save the document as [Save as Mobile Optimized Document], the included OLE object, Chart, Form Contols will be saved as images.

Terrible app from the Korean Internet ghetto


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 iOS's design philosophy, which is to hide the file system from the user.

I would go on, but let me leave you with a plea:
Don't 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 Microsoft's .doc and .docx format are better and that is a sad line to end this review with.

Thanks great app !


I use it for PDF , word, and most importantly as offline browser, and works great! I tried other apps but none is as good as this

A lifesaver!!


Long story short this app saved me a lot of trouble and headaches! I love it I'm so glad this is available thank you!!
