Score: 5.7/10 (Innovation: 6, Technical: 6, Documentation: 4, Utility: 5)

PTrace is an iPhone and Apple Watch running tracker that records GPS, motion sensor data, and heart rate, with support for importing runs from Apple Health and GPX/TCX/FIT files. Its key differentiator is an MCP (Model Context Protocol) integration that lets users connect their own AI assistants to query training history, generate charts, and create workouts directly within the app, with granular user-controlled data sharing permissions.

Target audience: Runners and fitness enthusiasts, particularly those interested in using AI assistants to analyze their training data
