Actually surprised by how fast the scanning is. I just point my camera at the dash, and it grabs the data immediately, no manual typing required. So much easier than writing to a spreadsheet. Can't wait for the household sharing update so my wife, and I can finally sync our logs.

Dev has done a phenomenal job making an easy to use yet powerful EV efficiency tracking tool. The OCR. Makes it simple to input each charge session. The cherry on top is that everything is local.
