Lucid Reader gives you a clean, distraction-free way to read PDFs — whether they're standard documents or books you've scanned yourself. No clutter, no complexity. Just your PDF and you.
*** Key Features ***
• Two-Page Spread — Read like a real book, with an optional standalone cover page.
• Flexible Binding — Switch between right-to-left or left-to-right binding, perfect for Japanese-style books and manga.
• Optimized Display — Fine-tune the display area and zoom independently for the left and right pages to maximize space and trim away margins.
• Intuitive Page Navigation — Turn pages effortlessly with a tap or a swipe, with customizable tap zones.
• Page Lock — Keep your view exactly where you set it and prevent accidental shifts.
• Full-Screen Mode — Fully immerse yourself with a distraction-free view.
• Collections — Group multiple files together for tidy, organized reading.
• iCloud Storage — Offload files to iCloud to reclaim space on your device.
*** Effortless File Access ***
Open PDFs in seconds:
• Tap the + icon in the top-right corner of the file list, or
• Choose "Save to Lucid Reader" from the share menu in any other app.
*** Secret Mode — Enhanced Privacy (In-App Purchase) ***
• Create more collections
• Protect your sensitive files with advanced privacy tools:
• File Hiding — Swipe right on any file and tap Secret to hide it from the list.
• Restricted Access — Hidden files stay concealed until you unlock them with Face ID / Touch ID, keeping them private even if someone glances at your screen.
• App Switcher Privacy — Secret-mode PDFs are blurred when switching apps, so your private content stays hidden even on the multitasking screen.
• End-to-End Encryption — Encrypt secret files with a password directly on your device. Your files remain unreadable without your password, even if your iCloud storage is accessed.
Experience the perfect balance of simplicity and control. Lucid Reader is built for one thing — hassle-free PDF reading.
