Hate reading PDFs at night? So did we. Eclipse is the dark mode PDF reader your eyes have been waiting for. One tap transforms any PDF into a beautiful, eye-friendly dark document — no more blinding white backgrounds in bed, on the couch, or during late-night study sessions. TRUE DARK MODE — NOT A FILTER Most apps just dim your screen. Eclipse is different. Our smart color inversion engine flips the actual content — white becomes black, black becomes white — giving you a true OLED-friendly dark reading experience that saves battery and protects your eyes. Choose from three reading themes: ◆ Pure Dark — Full inversion, maximum contrast, perfect for OLED ◆ Warm Dark — Soft tones for relaxed reading (Pro) ◆ Sepia — Paper-like warmth for long sessions (Pro) ANNOTATE & MARK UP YOUR DOCUMENTS Eclipse isn't just a viewer — it's your complete PDF workspace: ◆ Highlight text with a translucent highlighter ◆ Draw freehand with pen, marker, or highlighter tools ◆ Pick from multiple colors and adjust line thickness ◆ Undo strokes and erase individual annotations ◆ All changes are saved directly to the PDF file SMART READING FEATURES ◆ Bookmark any page with a custom title ◆ Full-text search across your entire document ◆ Go-to-page navigation for quick access ◆ Reading progress bar with page tracking ◆ Continue Reading — pick up exactly where you left off ◆ Screen brightness control built right in ◆ Share PDFs directly from the reader YOUR LIBRARY, ORGANIZED ◆ Import PDFs from Files, iCloud, email, or any app ◆ Thumbnail previews for every document ◆ Search your library by file name ◆ Delete documents with a long-press ◆ Clean, elegant interface — no clutter, no distractions 100% PRIVATE.
