CardFlow is an app that allows users to create and study flashcards. Users can create flashcards either through a rich text editor with both front/back and fill-in-the-blank options or by taking a picture of handwritten notes and masking out parts of the picture to occlude in the flashcard. Cards can be studied using a spaced repetition schedule based on user feedback given through a slider scale after each repetition. This creates a more personalized and efficient study experience.

Verdict

The call

The clearest difference is rating: Feyn at 4.3 against CardFlow's 3.8. Feyn also leads on review sentiment (80% vs 40%) and ratings volume (101 vs 12). CardFlow's advantage is in-app purchases (none vs 3) and iOS requirement (11.0 vs 16.1). On price, ads and device support there is nothing between them.
