Say what you ate. It's logged. Calorize is a calorie tracker with an AI assistant called Mira. No search, no forms — speak, type or point the camera, and the entry lands in your diary with calories and macros. WHAT MIRA DOES • Logs from plain speech — "eggs and coffee" goes into breakfast • Edits in the same chat — "remove the bread", "make it 400 g" • Copies meals — "same lunch as Monday" • Estimates the portion when you're vague • Learns your usual foods and portions from your own history YOUR DAY AND YOUR WEEK, READ BACK TO YOU Mira analyses what you actually ate and explains it: what's working, what's drifting, and the one change worth making. Supportive, never scolding. ALSO IN THE APP • Photo and barcode recognition • Recipe builder for your own dishes • Water, weight and body measurements • Workout log • Peptide protocols with a dose-to-syringe calculator ON YOUR APPLE WATCH • Watch app — tap, say what you ate, lower your wrist; it buzzes when the entry is in • Complications — today's calories on your watch face: circular, corner, inline or rectangular • Smart Stack — the same ring and count, one swipe from the watch face PLANS Free — the diary, the food database, recipes, and a starter allowance of Mira's chat.

Verdict
The clearest difference is in-app purchases: Openweight at none against Calorize's 4. Openweight also leads on ads (none vs shown) and iOS requirement (12.4 vs 15.0). Calorize's advantage is update cadence (every 2 weeks vs every 4 months) and device support (4 vs 2). On price there is nothing between them.
