BurnLedger

BurnLedger is a private, local-first food and fitness tracker for iPhone and iPad. Log calories, macros, water, exercise, and weight — everything stays on your device. No account, no sign-in, no servers, no ads. LOG FOOD HOWEVER YOU WANT • Snap a photo and AI splits the meal into per-item macros — protein, carbs, fat, calories, plus caffeine and sodium • Speak a description — voice transcription handles it • Scan a UPC barcode — Open Food Facts looks it up (no API key, no account) • Type it manually • Save favorites for one-tap re-logging • Adjust quantity after logging and macros rescale automatically YOUR CHOICE OF AI Bring your own API key from OpenAI, Anthropic (Claude), or Google (Gemini) — or use Apple's on-device Foundation Models with no API key and no network call. Requests go directly from your device to the provider you pick. You see the bill, not a middleman. WATER, EXERCISE & WEIGHT • Tap once to log water from the home-screen widget — works even when the app is closed • Live Activities track treadmill, outdoor walks/runs/rucks, cycling, and machine cardio on your lock screen and Dynamic Island • GPS records routes for outdoor sessions, with map share cards • Weight history with a four-week projection based on your actual intake vs. target INSIGHTS WITHOUT NAGGING • Weekly trends compare this week to last • Day-of-week pattern flags (e.g., "Sundays run hot") • Fasting timer that handles short eating windows or multi-day fasts • Daily and weekly recap summaries you can share TARGETS YOUR WAY Calorie and macro targets computed from your profile (Mifflin–St Jeor BMR × activity × goal) — or override any field manually. HOME-SCREEN WIDGETS Water, Calories, and Exercise widgets, three sizes each. The water widget can add a glass of water with one tap from the home screen. EXPORT YOUR DATA Export your entire history to a multi-sheet Excel (.xlsx) file at any time. It's your data. PRIVACY • No account, no sign-up, no servers • Everything stored in iOS-encrypted local storage • AI API keys live in iOS Keychain — only you can see them • Barcode scans send only the UPC to Open Food Facts (a non-profit open-data project) • "Erase All Data" in Profile wipes everything NOT INCLUDED • No subscriptions • No in-app purchases • No ads • No tracking SDKs • No "premium tier" One-time purchase.
