Read full description
DocOpen opens your documents without hijacking your screen. No pop-up ads. No forced video ads. No "watch this ad to continue" screens. Just a small banner at the bottom — that's it. ■ SUPPORTED FORMATS - PDF (.pdf) - Microsoft Word (.docx, .doc) - Microsoft Excel (.xlsx, .xls, .csv) - Microsoft PowerPoint (.pptx, .ppt) - Korean HWP (.hwp, .hwpx) - Plain text (.txt) One app for every major document format. ■ FEATURES - Banner ad only — no interruptions while you read - 100% offline — works without an internet connection - No account required — install and start reading - No tracking, no data collection — your files never leave your device - HWP support — most viewers can't open Korean .hwp files. DocOpen can. ■ REMOVE THE BANNER If the banner bothers you, a one-time purchase removes it forever. No subscription. No upsells. Buy once, done. ■ BUILT ON OPEN SOURCE - HWP support: rhwp (open-source HWP engine) - Office formats: LibreOffice rendering Open-source licenses are available in the "About" screen in the app. ■ WHO IT'S FOR - Anyone who deleted other doc viewers because of intrusive ads - People who receive Korean HWP files (students, expats, businesses working with Korea) - Users in areas with unstable internet — DocOpen works fully offline - Users who want a simple viewer with no sign-up - Privacy-conscious users who don't want files uploaded to the cloud ■ ABOUT THE DEVELOPER Built by Wick Labs — a solo developer who got tired of ad-heavy document viewers. Feedback and bug reports are always welcome.
