Just seen an advert for this but was too slow to catch a name or a link. Just indiegogo which seems to be some sort of kickstarter. Uses phone camera so i don't expect it to be too accurate. Fun for pub talk on who's smash is faster though. Anyone see or hear of it?
I saw the add to. It's by lingbu badminton. They have an iPad app already for something else, but I've never tried it. Here's the indiegogo link if I'm allowed to post it. https://www.indiegogo.com/projects/shuttle-speed-badminton-speed-calculator
