BlankStudy: Cloze Study

Stop rewriting your study material.
Cover what you need to remember and turn it into your own recall practice.

BlankStudy lets you place blanks directly on PDFs, photos, images, and text, then review them with active recall on iPhone and iPad. There is no account, advertising, subscription, or in-app purchase.

■ Make blanks your way
• Drag a box over any word, sentence, formula, or diagram
• Create write-in blanks and grade typed answers instantly
• Search a page and mask every matching term at once
• Paste a term-and-answer table to create blanks in batches

■ Focus on what you miss
• Track accuracy for every blank
• See strong blanks in green and weak blanks in red
• Review per-page statistics and filter by accuracy
• Retry only blanks below 80%, 60%, 40%, or 20%

■ Spaced review that adapts
FSRS-based scheduling brings difficult blanks back sooner and delays the ones you know. Optional on-device reminders tell you when a review is due.

■ Use your own material
• Import PDFs, photos, images, and text
• Automatically split long text into pages
• Organize with folders, favorites, cover colors, bookmarks, and notes
• Reveal mask groups together or step through blanks in tracking mode

■ Made for iPad and Apple Pencil
Write directly over your material with pressure- and tilt-sensitive ink, an eraser, and adjustable colors and widths.

■ Your material stays yours
BlankStudy saves locally first. If you sign in to iCloud, it can sync through your private CloudKit database across devices using the same Apple Account. Create password-protected backups or share a book through AirDrop and Files. The developer cannot view your study material.
