Mask Note: Image Occlusion

Mask Note turns any photo into a self-quiz. Cover the parts you need to memorize on a textbook page, your handwritten notes, an anatomy diagram, a map, or sheet music, then tap each mask to reveal the answer. It is image occlusion made simple: snap, mask, reveal, remember.

📷 Mask right on the photo
· Take a photo or pick one from your gallery, then cover what you want to learn
· Use rectangles or freeform polygon masks to match any shape
· Label each mask so you know what you are recalling
· Zoom and pan to cover small text precisely, and move or resize masks anytime
· Find text in the photo and tap a word or a line to mask it, processed on your device (Korean and English text)
· Pick several photos at once and turn them into notes in one folder (up to 20)
· Edit notes whenever you like: add, delete, relabel, with undo and redo

🎯 Tap to reveal and test yourself
· Sample notes are ready the first time you open the app
· Tap masks one by one in study mode to check your answer
· Four study modes: hide all, hide one, in order, and missed ones only
· Press and hold to peek, and mark what you missed to review just those next time
· Diagrams, labeled figures, maps, charts, and scores that are hard to turn into text flashcards stay as images

🔁 Review before you forget (spaced repetition, SM-2)
· Today's review picks the notes that are due and adjusts the next date by how hard each one felt
· Get a reminder on days when you have notes to review
· Set an exam date, folder, and daily goal to see what to study today
· Go over every note once more right before the exam

🗂 Folders and optional backup
· Organize notes by subject or exam
· Back up to your own Google Drive and share by link if you want
· Send a note to a friend as a file, and open notes you receive without signing in

🔒 Study stays on your device by default
· No sign-up. Photos and notes are processed and stored on your device by default
· Photo editing, text recognition, and study work offline
· Drive backup, if you choose it, sends photos and note data to your own Google cloud, and sharing goes through the app you pick
· Drive backups remain after you uninstall the app and can be deleted in Drive
· Ads, analytics, and text recognition SDKs may process identifiers and usage and diagnostic data

Great for
· Students with a lot to memorize for school, college entrance, licensing, or certification exams
· Medical, nursing, and health science students learning anatomy from figures
· Anyone memorizing maps, charts, vocabulary pages, or music

Stop just rereading. Cover it, reveal it, and make it stick. Free with ads.
