VeilStudy Diagram Recall

VeilStudy turns diagrams you already trust into focused active-recall sessions. Import an anatomy plate, map, machine drawing, music chart, or trade diagram, then place movable masks over the labels you want to learn. During study, say the hidden answer before revealing it. Mark Knew It or Missed and move through every mask at your own pace. The Progress screen keeps a deliberately simple local tally so you can return to what needs another pass. Every deck is editable. Change the title, subject, study note, source image, mask position, and answer label. Duplicate a deck to create a clean variation without rebuilding the diagram. VeilStudy does not provide study content, answer keys, medical advice, or professional certification. You choose the source material and verify its accuracy. Imported images, mask coordinates, and scores remain in the app container on your device. There is no account, subscription, in-app purchase, advertising, analytics, tracking, cloud sync, AI processing, or developer-server upload. VeilStudy is a one-time purchase for learners who want a quiet visual memory tool they control.
