App that measures pixels for cda Calcs

Hi team. There was an app mentioned on the podcast that can help estimate cda. I think it was Jonathon who talked through the process. You take a photo, it scrubs the background leaving the rider and bike then does the calculations. Does anyone recall the name of the app?

Bioracer Virtual Wind Tunnel?

Thanks Cartsman. That app looks interesting but that’s not it. Looks perfect for watching how your knees/hips track while pedalling though.
