    Hacker News commenters express skepticism about the accuracy and practicality of a calorie-counting app based on photos of food. Several users question the underlying technology and its ability to reliably assess nutritional content from images alone. Some highlight the difficulty of accounting for factors like portion size, ingredients hidden within a dish, and cooking methods. Others point out existing, more established nutritional databases and tracking apps, questioning the need for and viability of this new approach. A few commenters also raise concerns about potential privacy implications and the ethical considerations of encouraging potentially unhealthy dietary obsessions, particularly among younger users. There's a general sense of caution and doubt surrounding the app's claims, despite its popularity.
