ANCHOKO — hide any diagram, then learn it Image occlusion on your phone, free. Drop boxes over the labels on an anatomy plate, a circuit drawing or a map, and each box becomes its own card. IMAGE OCCLUSION THAT ACTUALLY WORKS ON A PHONE • Draw rectangles, ellipses or free-form shapes over any picture • Each shape becomes a separate card, so one diagram teaches you twenty things • Pinch to zoom while you place shapes — small labels stay reachable • Show the other boxes while you answer, or hide them • Works on photos, screenshots, textbook scans and imported PDF pages BRING YOUR ANKI DECKS • Import .apkg files and keep your cards, your images and your deck names • Cloze deletions come across as cloze deletions • Image occlusion notes keep their boxes, on the right part of the picture • Note types ANCHOKO does not know are still imported, front and back — nothing is lost • You are told what changed during the import. No silent edits PHOTOGRAPH A PAGE, GET CARDS • Photograph notes, a textbook or a handout and the text is read on your device • Cards follow the page layout — "term: meaning", "word translation", numbered lists • You see the recognised text before any card is made, so misreads never become cards RED AND COLOURED TEXT, FOUND FOR YOU • Anything written in red pen or pink highlighter is detected and covered automatically • Switch to green, blue or yellow when that is what you used • Popular with students in Japan, who use a red filter sheet for exactly this REVIEW AT THE RIGHT MOMENT • The SM-2 algorithm works out, card by card, when you are about to forget • Four ratings — Again, Hard, Good, Easy — reshape the interval • See your forgetting curve and how much is left • Cap how many new cards appear each day HANDS-FREE BROWSING Cards flip themselves at timings you choose, with read-aloud for commutes. Auto-advance never grades your cards, so your review schedule stays intact. • Also: cloze deletions, and annotations written straight onto a picture YOUR PHOTOS STAY ON YOUR DEVICE Text recognition, red-text detection and PDF rendering all happen on your device. Photos and PDFs never reach an ANCHOKO server.

Signing in later keeps everything you already made SAMPLE DECKS, ONLY IF YOU WANT THEM Nothing is added behind your back.

Verdict
The clearest difference is in-app purchases: Stuudy at none against ANCHOKO's 1. ANCHOKO's advantage is update cadence (every 2 weeks vs every 4 months) and iOS requirement (13.0 vs 17.0). On price, ads and device support there is nothing between them.
