Guaco

Counting calories used to be homework. With Guaco, it's a photo. SNAP. Point your camera at any meal and AI identifies every food on the plate, estimates portions, and logs calories, protein, carbs, fat, sugar and fiber — in seconds. Not a photo person? Describe your meal in a sentence, scan a barcode, search the food database, or enter it manually. TRACK. Your day at a glance: a friendly calorie ring, animated macro bars, water glasses you can tap to fill, and a weight chart that shows your trend toward your goal. Add the home screen widget and Live Activity to see your progress without opening the app. STAY ON IT. Daily reminders keep you logging, streaks keep you honest, and 10 achievements celebrate the wins — from your first scan to a 30-day streak. Sync everything to Apple Health with one switch. YOUR PLAN. Tell Guaco your goal — lose, maintain, or gain — and it builds daily targets from your profile, then adjusts them automatically as your weight changes. FREE VS PRO • Free: 3 AI scans per day + unlimited barcode scanning, food search and manual logging • Guaco Pro: unlimited AI scans — monthly or yearly, with a free trial PRIVATE BY DESIGN No account. No ads. No trackers. Your data lives on your device; meal photos are processed only to estimate nutrition and never stored. Nutrition estimates are AI-generated and approximate. Guaco is a wellness tool, not medical advice. Terms: https://guaco-proxy.guaco.workers.dev/terms Privacy: https://guaco-proxy.guaco.workers.dev/privacy

Verdict
The clearest difference is update cadence: Guaco at every 10 days against UpDown's every 4 weeks. UpDown's advantage is device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
