IDENTIFY EVERY SHELL YOU FIND Point your camera at a shell and ShellMap tells you what it is: common name, scientific name, family, how rare it is, and which coastlines it comes from. Then it cuts the shell out of the photo and turns it into a sticker on your own private shelf. SNAP AND KNOW - Opens straight into the camera, or pick a photo from your library - The shell is lifted out of its background automatically, no tracing - A full report: species, family, rarity, typical size, habitat and known regions - Honest about doubt: when a worn or broken shell cannot be pinned down, ShellMap says so instead of inventing a species YOUR OWN COLLECTION - Every shell becomes a die-cut sticker on a paper shelf - Tap any shell for its full field-guide entry - Add your own notes: the tide, the weather, who you were with - A private map shows exactly where you picked each one up COMPLETELY PRIVATE - No account, no profile, no feed, no followers - Your shells sync between your own devices through your iCloud, and nowhere else - Nothing is ever shared or made public - Free, with no limits and nothing to unlock WORKS ON THE BEACH Shells save instantly, even with no signal.
