# BiteDeck > A local-first iPhone nutrition tracker. No account. No ads. Photo scan, 117,012 foods, 179 restaurant chains, Apple Health bidirectional sync, on-device weight forecasting, intermittent fasting, body fat tracking, and a Coach assistant that runs without training on your meals. BiteDeck is built for iPhone (iOS 17+) only — no iPad layout, no Apple Watch app, no Android, no web client. The whole design leans on iOS-specific primitives: HealthKit, SwiftUI, SwiftData, and a Gemini Vision proxy for food photo recognition. Privacy is the lead promise. Logs live in SwiftData on the user's device. There is no BiteDeck server, no account, no telemetry, no analytics, no ads, no third-party scripts on the marketing site. HealthKit is the only external integration, and it's per-metric opt-in. ## Site map - [Home](https://bitedeck.app/): hero, proof stats, six-feature spec sheet, design system showcase, 10-question FAQ - [Privacy](https://bitedeck.app/privacy): what BiteDeck does and doesn't collect, off-device exceptions, HealthKit, export, erase - [Terms](https://bitedeck.app/terms): plain-English terms of service - [Support](https://bitedeck.app/support): support@bitedeck.app and feedback@bitedeck.app, full FAQ embedded - [Coming Soon](https://bitedeck.app/coming-soon): App Store launch placeholder (noindex) ## Coming next (in development) - /local-first: pillar page on what local-first means in a nutrition app - /about: brand authority + standalone Organization schema - /vs/myfitnesspal, /vs/foodnoms: honest comparison pages - /apple-health, /forecast, /fasting: feature deep-dives - /tools/tdee, /tools/body-fat-navy, /tools/katch-mcardle: free interactive calculators - /restaurants, /restaurants/[chain]: 179 chains with menus ## Stats - 117,012 foods in the local database - 179 restaurant chains - 1,195 brands (chains + packaged) - 5 HealthKit reads, 10 HealthKit writes - 5-state on-device weight forecast (Katch-McArdle, 14-day lookback, 7-day rolling avg) - 4 body fat estimation methods (US Navy, Deurenberg, manual, Apple Health import) - 4 intermittent fasting protocols (16:8, 18:6, 20:4, OMAD) plus custom 1–72h - iPhone only · iOS 17+ · Free tier + paid tier (price TBD)
