Score: 6.0/10 (Innovation: 7, Technical: 6, Documentation: 4, Utility: 5)

Species.app is a visual spaced-repetition engine designed specifically for learning taxonomy, using perceptual interleaving to show visually similar species back-to-back to train identification skills. It's interesting because it adapts the FSRS algorithm for image-heavy learning, addressing a gap where traditional text-based flashcards fail for visual domains like naturalist studies.

Target audience: students, educators, amateur naturalists, biologists
