Shell Spiral Tracker-Snail

This is a quiet wilderness note taking app suitable for all those who are fascinated by snail shell spirals. Take a photo of the shell and record whether the spiral is right-handed or left-handed. Every observation will be saved on your device, including photos, variety, shell width, location, and notes. After associating the record with the variety file, the app will instantly summarize the rotation pattern of the variety, making it easier for you to discover unconventional "reverse individuals". Whether you are a student, a nature enthusiast, or simply curious, you can turn a garden walk into a small scientific observation.
