17 Fit vs Cal AI
Cal AI is one of the best-known photo calorie counters: photo, barcode and text logging in one simple app, rated 4.8 by more than 370,000 people on the US App Store, and on Android too. Logging food opens a paywall: after a 3‑day trial it takes a subscription. 17 Fit counts a meal from a photo or your voice on its free plan, and adds an AI coach and a target that learns from your weight trend.
