One of us who works at the tech desk may have eaten five pieces of pizza last night — without any awareness of the total calories. It might have been a good opportunity to use Cal AI, an app where users can upload a photo of their meal and receive a calorie count that has a purported 90% accuracy. Cal AI isn’t the first digital calorie counter, but it has a 4.8-star rating on the Apple App Store and over 1 million downloads on Google Play. @Techcrunch has more on this app developed by a pair of teenagers.
