## Description

Turn your everyday notes into flashcards — just by taking a photo.

Red Sheet Camera hides the answers you wrote in red or orange pen (and green highlighter), so you can quiz yourself just like a physical red memorization sheet.

HOW IT WORKS — 3 EASY STEPS
1. Scan your notes or textbook (auto-straightened)
2. Red-pen answers get hidden by the sheet
3. Tap or slide the sheet to reveal the answers

FEATURES
- A real red sheet, digitized
The same idea as a physical red sheet: red and orange pen disappear, while black and blue text stays readable.

- Auto-Hide
Tap "Auto-Hide" to detect red/orange pen and green highlighter and cover them automatically. Fine-tune the hidden areas by tap or drag.

- Organize by subject
Keep a separate notebook for each subject — biology, history, English, math and more.

- Fully on-device
Everything works offline, and your photos stay on your device.

Perfect for exam prep, vocabulary, dates, formulas and anything you need to memorize.

PRO (ONE-TIME PURCHASE)
Scanning, hiding and studying with the red sheet stay free, always.
With Pro:
- The parts you could not recall are remembered
- Next time, review only those parts
- See how many rounds you have done and how much you recalled
- No ads
One payment. Restore it for free after changing or reinstalling your device.
