WoofNote turns the questions you got wrong into your own review notes. Saw a question you missed on a test, glanced at it once, and moved on? You'll probably miss it again.

Take a photo of the question you got wrong. 2. AI reconstructs it into a review note. 3. Each evening, review the questions due that day. [Why you'll love it] β€’ Just add a photo β€” your questions are organized automatically. β€’ Spaced repetition (SRS) brings each one back right before you forget it. β€’ It tells apart what you know from what you don't, and reviews the hard ones more often. β€’ A daily 6 PM reminder tells you what's due to review. Get a question wrong once, never again. Create your first review note now. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
