PI-Link Speed Radar

Additional capabilities include structured training missions and multi-player management. The app features guided baseball development workflows that turn speed readings into purposeful training sessions, offering daily missions and performance context within a unified training hub. Users can create and switch between multiple player profiles, keeping units, data, and session context neatly organized for teams or individual athletes. The app also provides a library for browsing, favoriting, and sharing recorded clips, visualizations like strike zone context, calendar analytics for progress tracking, and more training controls such as voice announcements, auto-save, 120FPS recording, and data export options, creating a complete mobile-first training environment.

PI-Link works through a four-step technical process engineered for reliability. First, the radar module emits a 24 GHz K-band Doppler signal to capture motion within its field of view. Second, the module's signal processing generates a set of speed candidates from the detected Doppler shift, covering the measured range. Third, the connected smartphone's compute power analyzes these candidates, applying filters to discard reflections and false reads, thereby isolating the most reliable measurement. Finally, PI-Link outputs a clean, single speed reading on the app's display, accompanied by a synchronized video clip if recording was enabled during the session, completing the cycle from signal detection to actionable result.

The benefits and measurable outcomes for users are substantial. Athletes and coaches gain a portable, affordable speed radar that integrates directly into their existing smartphone ecosystem, eliminating the need for separate, expensive hardware. They receive not just velocity numbers but automatically generated video clips paired with each reading, enabling detailed technique review. The system maintains comprehensive historical records, allowing for precise tracking of performance trends and training volume over days, weeks, and months. This data-driven approach supports structured player development, helping to optimize bullpen sessions, arm-care programs, and long-toss routines with concrete, reviewable metrics and visual feedback.

Concrete use cases include bullpen pitching sessions where a coach can measure each pitch's velocity while simultaneously recording video for immediate or later review. For player development on the field, athletes can use PI-Link during long-toss or throwing practice to track speed progress and maintain a personal velocity log. In arm-care and training workflows, the training missions feature can guide specific drills based on historical performance data. For team environments, the multi-player management allows coaches to swiftly switch between athlete profiles, keeping each player's data, preferred units, and session history separate and organized, all from a single smartphone and module.

The target users are baseball athletes, pitching coaches, player development staff, and training facilities seeking a modern, connected speed measurement solution. It integrates with the user's existing iOS or Android smartphone tech stack, requiring no additional standalone hardware. The product was validated through a successful Kickstarter campaign, raising $80,340 from 511 backers and achieving 4,017% of its funding goal, with additional regional crowdfunding planned for Korea (Wadiz), Japan (Makuake), and Taiwan (Zeczec), plus global post-campaign access via Indiegogo Pledge Manager. Pricing plans are not explicitly detailed in the provided content, but the campaign traction indicates strong market demand for this innovative approach.

In summary, PI-Link represents a fundamental shift in sports radar technology by modularizing the hardware and leveraging ubiquitous smartphone power. It moves beyond being a simple measurement tool to become an integrated partner in baseball training, combining reliable Doppler radar sensing with a powerful app that manages video, data, history, and guided improvement. The product validates its concept through successful public funding and is purpose-built to fit naturally into the mobile-first, data-driven workflows of modern athletes and coaches, offering a comprehensive solution for measuring, reviewing, and improving pitching performance.
