Badminton Speed Meter is a private badminton training utility for estimating shuttle speed from your own video clips. Choose a training video from your photo library, upload it for private analysis, select the impact frame, mark the shuttle position, and receive an estimated speed in km/h. The app is built for personal training reference. You can review previous analyses in history and delete uploaded videos from cloud storage when you no longer need them. Speed results depend on video clarity, frame rate, camera angle, lighting, court visibility, and marking precision. Results are estimates only and are not certified measurements for competitions, rankings, betting, medical use, or official records.
