ArchFix is a mobile application that allows users to determine if they possibly have flatfoot and provides tailored preventive or corrective exercises based on a footprint image. Footprints can be created at home using a piece of paper and either colours or a wet foot. The foot analysis is performed using an algorithm that first detects the footprint from the uploaded photograph and then analyses it using established orthopaedic methods for footprint processing.

Users can access their results and track progress over time. If the analysis indicates that the issue cannot be resolved at home, the application provides recommendations for nearby healthcare institutions. Additionally, users can gain detailed insights into their condition and set reminders for regular exercises and rescanning to ensure faster progress and more accurate tracking.
