Mekurin: Red Sheet Study

No page limits. No subscription. No ads with sound.
Snap your textbook, vocabulary list or notes, and red ink disappears just like under a real red sheet.

■ Works like a real red sheet
Under the sheet, the page is redrawn with red light only. Red, orange and pink ink turns the same color as the paper and vanishes, while black and blue text stays dark and readable. Nothing gets inverted or washed out.
Use the "Fade strength" slider for light red pens or darker photos.

■ Move the sheet with your finger
Drag the red sheet up and down and resize it from its bottom edge. Its position, height and fade strength are saved for each note.

■ Drag to hide, tap to reveal
In Hide mode, drag over any part to cover it with a box (orange, blue or gray).
In Study mode, tap a box to reveal it, tap again to hide it, or reveal everything at once.
Zooming in Study mode never draws anything, so boxes don't appear or move by accident.

■ Import in seconds
Take a photo or pick many photos at once. Pages are saved on your device; rotate, reorder or delete them anytime. Organize notes into color-coded folders for each subject.

■ Known / Weak marks
Mark each page as Known or Weak. The list shows how many pages you know.

■ Free forever
No limits on photos or notes. The red sheet, hiding boxes, marks and folders will always be free.
Ads appear only as a banner on the home screen and when you finish a note — never while you study, and never with sound.
