## What is 赤シートくん?

Red Sheet-kun is a red-sheet style study app that lets you hide answers in textbooks, worksheets, notes, photos, scans, and PDF materials. You can overlay a red sheet on the live camera view, import scans, images, or PDFs, save them as files, and review them later with red, green, or blue sheets, markers, pen, and text. It is useful for vocabulary, exams, qualification study, and memorization with paper materials without remaking your usual worksheets. Optional subscriptions remove usage limits and ads. Subscriptions renew automatically unless canceled, and can be managed or canceled in your App Store account settings.
