10月20日的Boba: Local AI Calorie Tracker应用程序分析

Boba is the first local AI calorie tracker that runs entirely on your phone. Point your camera at food. Get calories, protein, carbs, and fat in seconds. No cloud. No account. No subscription. Ever. We built Boba because we were tired of calorie apps that hide basic features behind $30-a-year paywalls, send every photo of your lunch to someone else's server, and still get half your food identifications wrong. Boba is different by design. HOW IT WORKS 1. Open the app. 2. Point your camera at food. 3. Get calories and macros in a few seconds. 4. Log it to your day. That's it. No account, no email, no credit card, no paywall. ON-DEVICE AI Boba runs a 2-billion parameter vision-language model, fine-tuned on a custom food dataset. The entire model ships inside the app — bundled at install time, no first-launch download, no cloud calls at inference. Everything happens on your iPhone's Neural Engine. Test set accuracy: 89.8 calorie MAE. The best on-device food AI we could build. PRIVACY BY ARCHITECTURE Boba doesn't collect your data because the app is designed so it can't. There are no Boba servers that receive your photos. There is no user database. There are no analytics. The only outbound request the app ever makes is to Open Food Facts when you scan a barcode — and that query contains only the barcode digits, nothing else. Your meals, weight, goals, and photos stay on your phone. Delete the app and everything is gone. That is the entire data flow. WHAT'S INCLUDED • AI food scanner — camera → calories in seconds • Barcode scanner — Open Food Facts integration • Manual meal entry • Daily calorie + macro tracking • Water tracking • Weight tracking • Intermittent fasting timer • Dark mode • Export all your data anytime No ads. No subscriptions. No tracking. No paywalls on core features. Ever. WHO IT'S FOR • People who want to lose, gain, or maintain weight without the corporate tracker experience • Anyone allergic to subscriptions and dark patterns • Privacy-conscious users who don't want their eating habits logged to a server • Gym-goers who track macros • Intermittent fasters • Anyone who believes calorie tracking shouldn't cost $30 a year ABOUT THE MODEL Boba's vision model is a fine-tuned 2B VLM built by Doses AI. It identifies dishes, estimates portions, and outputs per-item nutrition locally. We'll improve it over time. Future major model upgrades may be offered as optional in-app upgrades, but the core app — scanning, logging, tracking - will always be free. IMPORTANT Boba is a wellness tool, not a medical device. Calorie and macro estimates are AI approximations and may be inaccurate. Boba does not diagnose, treat, or prevent any disease.
