Nail Cloud is a digital “nail passport” that helps users manage their nail care in a safer and more personalized way by storing nail sizes, product history, allergies, and past designs. It also includes a virtual try-on feature so users can preview nail styles on their own hands before booking services or ordering press-ons. The platform addresses common issues like inaccurate sizing, poor color matching, and limited awareness of nail product safety, including gel-related allergies.
