PRIVACY-FIRST & COMPLETELY LOCAL

No Accounts Required: Skip the sign-up process. Open the app and start tracking immediately.

100% Offline Storage: Powered by a secure local SQLite database, the app requires no cloud sync or active internet connection to browse your history.

Your Data is Yours: Easily export your full database as a JSON file or get a spreadsheet-compatible CSV summary of your daily macros whenever you want. DEEP NUTRIENT & MACRO TRACKING

Track up to 17 essential nutrients per food entry, including:

Macros: Calories, Protein, Carbohydrates, Fat.

Sub-Macros: Fiber, Sugar, Saturated Fat, Trans Fat, Cholesterol.

Minerals & Vitamins: Sodium, Potassium, Calcium, Iron, Vitamin A, Vitamin C, Vitamin D, and Water. CUSTOMIZABLE HOME SCREEN

Concentric Progress Rings: Visualize your day at a glance. Calories are always pinned to the outer ring, and you can pick and order up to 4 metrics to track as rings.

Dynamic Macro Row: See real-time numeric progress (e.g., "82g / 150g Protein") right below your charts.

Flexible Meal Logging: Preload your day with a custom number of meals and personalized names (e.g., Breakfast, Lunch, Dinner, Snacks). Adjust, rename, or log on the fly via the quick-add sheet. EFFORTLESS FOOD LOGGING

Smart Search & Barcode Scanning: Search a massive database of foods or instantly look up items using your device's camera to scan barcodes.

AI Photo Recognition (Optional): Snap a photo of any meal and let AI estimate its name, calories, macros, and portion size. These are pre-filled into the food editor for you to review before saving. This feature uses your own API key (instant validation, no markup), and photos go directly from your device to the AI provider and never through our servers.

Scale with Ease: All 17 tracked nutrients automatically scale to your precise serving size adjustments.

Custom Dishes Library: Build a personal recipe catalog. Group multiple ingredients together into a "Dish" with custom serving multipliers to log complex home-cooked meals in a single tap. SMART WATER TRACKING

Track your daily hydration in your preferred unit: Cups, Fluid Ounces, or Liters.

Quick-add buttons dynamically adjust based on your selected unit for painless logging.

Includes an instant "undo" button for the last logged entry. POWERFUL REPORTS & INSIGHTS

Analyze your progress over rolling 7-day or 30-day periods with charts that only count the days you actually log—preventing empty days from skewing your averages:

Calorie & Macro Trends: Clear bar and line charts complete with overlayed goal lines.

Consistency Metrics: Monitor your current logging streak, longest streak, and total active days.

Historical Breakdown: Dive into past entries via the calendar view to review specific dates and meal-by-meal breakdowns. MULTI-PROFILE SUPPORT

Perfect for families, changing fitness phases, or cycling goals. Create multiple independent profiles—each with its own dedicated name and a completely unique set of nutrient targets. Switch active profiles seamlessly at any time. ACCESSIBILITY & COMFORT

Tailor the app to your environment with full support for Light Mode, Dark Mode, System theme matching, dynamic font scaling, and a high-contrast toggle. Fully optimized for both iPhone and iPad layouts.
