"As a biology teacher, I’ve been using the Classic version for years. It’s an indispensable tool for my field trips. There’s nothing more rewarding than seeing my students’ faces light up when they realize their photos are actually helping scientists track local biodiversity. It turns every hike into a meaningful contribution to global conservation."

Sarah J., High School Educator

"I love the simplicity of iNaturalist Classic. It’s like having a professional naturalist in my pocket while I’m out in my garden or exploring local trails. The community is incredibly helpful—I’ve learned so much about the native plants in my area just from the identifications provided by other enthusiasts. It has completely changed how I see the nature around me."
