Smashspeed

👋 Hey everyone! I’m Diwen, a 16-year-old badminton player and certified coach. I built Smashspeed because I wanted an easy, accessible way for players—especially juniors and those without access to expensive gear—to track and improve their smash. Most radar-based tools are either too pricey or hard to find. So I created a solution that uses just your phone and AI to calculate shuttle speed and angle, using video from a simple side view. I’m actively adding features based on community suggestions—so far I’ve implemented things like angle tracking, Google login, and better explanations of how smash speed is calculated. I’m always looking to improve, so your ideas or feedback would mean a lot. What features would make this app more useful to you? Let me know—thanks for checking it out!
