My kids' elementary school has a running club that I manage. In past years they pay a subscription to a company that's quite expensive to track laps. I decided to implement some software that's better and runs on an rpi.

It's working very well, and the kids like it more because it has audio feedback on laps and time.

Besides the cheap USB qr scanners there's no expenses either.

I don't need this app, but sounds look a cool project? Can you share more details? How does it tack laps?

Thanks for the interest. I will post it publicly soon, but right now it's on my private github. Basically it's a small python app running on a raspberry pi with 2 USB QR scanners. It uses sqlite with a database of QR codes assigned to the students. They wear lanyards with those codes on them. When they start running it logs their start, and every lap they can again. It tracks personal records, total laps, laps per day, and time per lap.

We've received a lot of positive feedback from the kids compared to the old system that was using proprietary software. The problem with that software is it used cell phones for scanning codes, which is very error-prone and takes a long time to register on some phones.
