fixin for iOS is the complete product. Every other platform is measured against it. The diagnosis engine runs entirely on your iPhone or iPad — your photos are never uploaded to be identified, and a diagnosis works the same in a parking garage with no bars as it does on wifi.
Point the camera at the problem. The Sapphire 4.3 engine returns a ranked set of likely causes with confidence attached, the checks that confirm or rule each one out, and the specific parts you'd need if it's right. If the job should go to a professional, hirin hands it off instead of talking you into it.
"No way it is that easy to use..."
— Scott M.
Sapphire 4.3 landed with 1.4.2. A full retrain that reads the broad category correctly 89% of the time, up from 83%, and lands the specific area 48% of the time, up from 36% — roughly a third more correct diagnoses than the engine in 1.4.0. It also brings close alternatives: when the model can't cleanly separate two categories it lists them in order with their confidence rather than showing only the winner.
