Hi, I'm Andi, one of the developers of Photo Finish and I'm absolutely thrilled to share Photo Finish here on Product Hunt! As semi-pro 800m runners ourselves, we knew the struggle with pricey, clunky timing gear. Our club didn't even have the money to afford a light barrier system. So we built Photo Finish - an affordable and accurate timer right on your phone. Would love to hear your thoughts and get any feedback you have!

As an ex-track athlete, I love this. Training before tech, it was always hard to get accurate times on trials and training. Looking forward to testing this out!

This is so cool! Will this work for Karting as well? It would be great to have a share feature as well! Congrats!

@chandula Thank you for your compliments! We currently mainly target track and field. It might just work with karting, but there are some limitations: - Currently, you could measure lap times of a driver, but no races are possible, because we can only detect one athlete at a time. - We currently reach an accuracy of 0.01s-0.02s depending on your os type. So just centisecond and no millisecond accuracy. I don't know much about the timing of karting and if that would be an issue. In your case, you could just try out the free basic mode and see if the detection works with karts and the accuracy meets your needs. Would love to hear about your experience! What do you mean with "share feature"?

@acplewnia I will try it out for sure the next time I go karting! What I meant by a 'share feature' is a feature that would let me share my timing with a friend.
