About this app
Digital Red Sheet Memorization App for PDFs, Photos & Flashcards
Memorize faster with “hide & reveal” study sheets — anywhere, anytime.
Turn any PDF or image into a red-sheet style memorization sheet.
Hide only what you need, scroll smoothly across pages, and review on the go — even on the train.
Key features
- Hide by color (red, blue, orange, and more)
- Flexible blocks: adjust shape & size to hide any area precisely
- Vertical scrolling: memorize across multiple pages without flipping
- Lighten the hidden color so black text stays readable while memorizing
- Study together: original colors to hide + blocks you create
All-in-one memorization
- PDF memorization: import PDFs and build your own red-sheet study book (works even without color)
- Photo memorization: hide words from notebook photos, handouts, or whiteboards like a digital marker
- Flashcards / word lists: build vocabulary lists and memorize efficiently
How it works
1) Import a PDF or add photos
2) Hide what you want to memorize (by color or by blocks)
3) Tap to show/hide and test yourself instantly
4) Scroll and repeat — quick reviews anytime
Powerful study tools
- One-tap show/hide for self-testing
- Create multiple blocks quickly for consecutive items
- Auto-align blocks for a clean, organized sheet
- Zoom in/out without losing alignment
- Swipe to move between images / add new photos easily
- (If available) Record audio on a hidden block to memorize pronunciation
Great for
- Exam prep / test review / entrance exams
- Language learning: vocabulary, phrases, grammar
- Certifications and professional study
- Any subject that needs memorization: definitions, formulas, notes
