In/Out Tennis

Very good progress so far. I mainly use the device to measure my serve speeds. Metrics are recorded and can be opened in Excel or Google Sheets. However, a lot of my serves don't register for some reason despite being moderate speeds. The device is very buggy but it improves all the time, and there's no other device quite like it. My biggest gripe regarding the app is that I can't download my video recordings via the app. I have to download via Google Chrome, via usb cable, or via microSD.

As other user have stated: I really wanted to like this thing. Early adopter and while it works and has been improved through updates the build quality of the first generation device is pretty lacking. Can't speak for subsequent models but buy at your own risk. After replacing the battery (the micro USB port just popped out) I was completely disappointed when the housing opened and one of the cameras popped out. Managed to close it but broken. Treat like an egg. Assume if dropped, its done

i think this is now abandoned, unfortunately
