ArchFix is a mobile application that helps users identify potential signs of flatfoot and supports maintaining healthy feet through guided exercise programs. The app allows users to easily create and analyze their own footprint at home using just a piece of paper and either paint or a wet foot. The uploaded photo is processed by an algorithm that detects the footprint and evaluates it using established orthopedic assessment methods. In addition, ArchFix provides a collection of preventive and corrective exercises presented through videos and step-by-step text instructions. Users can create their own personalized exercise plans, schedule reminders, and track progress over time through repeated footprint scans. Disclaimer: ArchFix is not a substitute for professional medical diagnosis or treatment. It is designed to help users self-assess potential flatfoot conditions or support those already diagnosed in maintaining a regular exercise routine.
