Null Reader
A small Android reader for EPUB, PDF, Markdown and TXT. It opens your files, remembers where you stopped and otherwise stays out of the way.
Offline first
No account, cloud backend or connection required to read your files.
Quiet by design
No ads, analytics, tracking, social layer or recommendation feed.
Four formats
EPUB, PDF, Markdown and plain text, split into simple dedicated library views.
Your files stay yours
Null Reader uses Android's document access system and does not delete source files when removing library entries.
Reading, not managing
Text size, line spacing and margins are adjustable. Dark, light and warm Compass profiles are built in. PDF pages support navigation, saved position and pinch-to-zoom.
Direct APK
This beta is signed with Null Reader's permanent release key. Android may still display an installation warning because the APK is installed outside Google Play — that is normal for sideloaded applications.

Current status
Null Reader is now in public beta. EPUB metadata and Android “Open with…” integration are working; the next stage focuses on library polish, wider device testing and bug fixing.
