FAQ
Is it free?
It is free today. Ads or an optional paid plan that removes them may be added later; if that happens, we will say so in the app description and the privacy policy first.
Can I edit documents?
No. It is a read-only viewer, and your original files are never changed.
Will HWP and PowerPoint files look exactly like the original?
Text, tables and images are shown, but some formatting such as shapes, equations, charts and animations may not appear. When something cannot be shown, a notice appears above the document.
Can it open password-protected files?
Not yet. You will see a message that password-protected files are not supported.
Is there an iPhone version?
Not at the moment. The app is for Android only.
