Snap your textbook. Hide what you want to learn. That's it. You don't have time to make flashcards from scratch. FlashSnap solves that. Take a photo of any page, brush over the key words with a marker, and your personal study sheet is ready in seconds.

The familiar paper red-sheet method, now on your phone — with a little extra intelligence.

What you can do 【Photo Sheet】 Photograph textbooks, notebooks, or any printed material. Cover important words with red, blue, or green markers. During study, the markers hide the answers — tap to reveal.

【Classic Cards】 Front-and-back cards with images or text. Perfect for vocabulary or matching pairs.

【Text Cards】 Simple Q&A format. Great for formulas, definitions, or quick facts.

【Spaced Repetition (SM-2)】 The cards you remember well come back later. The ones you struggle with come back soon. Backed by proven memory science.

【Exam Forecast】 Set your exam date and FlashSnap calculates whether you're on pace to finish. Warnings appear if you're falling behind, so you can adjust early.

【Weak Cards Highlight】 The cards you keep missing are surfaced automatically. Focus your review where it matters.
