Kakushi vs Red Sheet Camera

Kakushi turns any photo into a reusable study sheet. Paper red sheets only work on specially printed text. Highlighter pens are permanent and ruin your notes. Kakushi solves both: photograph any page, notebook, or textbook, brush thick black marks over the words you want to memorize, and tap each mark to reveal the answer. Tap again to hide it and test yourself once more — as many times as you like. No typing. No setup. Just snap, brush, and tap. WHY KAKUSHI - Works on anything: your own notes, printed handouts, photos, textbooks - Precise tap to reveal: open one answer at a time, not the whole page - Freehand strokes, rectangles, and lines to cover exactly what you need - Reveal all or hide all in a single tap for a full run-through - Organize sheets into folders like "English Quiz" or "History Dates" - Gentle review reminders so you look again before you forget HOW IT WORKS 1. Take a photo or pick one from your library 2. Brush black marks over what you want to memorize 3. Open Study mode and tap each mark to check your answer KAKUSHI PRO Create unlimited study sheets with no ads, as a monthly plan or a one-time lifetime purchase.
