Nutrient Logger is the offline-first nutrition tracker for people who want to know what's actually in their food - not just calories and macros, but the full spectrum of vitamins, minerals, and amino acids your body needs. Unlike cloud-based trackers, your food log never leaves your device - no account, no cloud, and no ads. And unlike macro-focused apps, every entry breaks down 80+ nutrients so you can spot gaps before they become deficiencies. Key Features: * Personalized From Day One Tell us how you eat - balanced, plant-based, keto or low-carb, carnivore, or pescatarian - and what you care about most, from energy to bone and joint health. Nutrient Logger moves the nutrients you're most likely to run low on to the top of your Nutrition tab, so the gaps that matter to you are the first thing you see. Change your answers anytime in settings. * Detailed Nutrient Breakdown See your daily intake of both macro and micronutrients, from protein and fiber to magnesium and vitamin B12. Choose which nutrients matter to you, reorder them, and set how many each group shows at a glance to build a Nutrition tab that fits your goals. * Barcode Scanner Scan any packaged food to instantly pull in its nutrition data. If we don't recognize a barcode, you can search manually or add it as a custom food - nothing stops you from logging. * Extensive Food Database Search from tens of thousands of foods, including whole ingredients and packaged items, to log meals with precision. Smart search understands what you mean - type "whole milk" and find it instantly, even expand common shortcuts like "OJ" or "PB". * Log Anything Scan barcodes, search our database, or add your own - and save your go-to meals for faster logging next time. * Personalized Targets Set your own calorie, macro, and micronutrient goals - or use recommended daily values based on your age and sex. Track your progress and stay balanced, with trend charts for calories, macros, and water alongside every nutrient. * Water Tracking Log water with one tap and watch an animated tracker fill toward your daily goal. See your hydration trends over 7 or 30 days (Premium). * Body Metrics & Goals (Premium) Track weight, body fat, BMI, and waist circumference - pick which ones matter to you. Set a goal and deadline and Nutrient Logger calculates the pace you need, projects your trajectory, and sets a BMR/TDEE-based calorie target to get you there. * Streaks & Achievements Build a daily logging streak and a weekly body-tracking streak, with milestone celebrations along the way. See your longest streak, total days logged, and more on your profile. * Nutrient Trend Charts (Premium) See how your intake of any nutrient changes over 7 or 30 days. Spot patterns, track consistency, and compare against your daily target. * Weekly Deficiency Insights (Premium) A weekly digest flags the nutrients you've been running low on, with foods that would help close the gap. * Apple Health Sync (Premium) Automatically write your daily calories, protein, fat, carbs, and water to Apple Health. Import weight data from Health to keep everything in one place. * CSV Export (Premium) Export your full food log with nutrient data for any date range - ideal for sharing with a doctor or dietitian. * Learn as You Log Discover what each nutrient does for your body and why it matters to your overall health. Nutrient Logger is perfect for anyone serious about nutrition-whether you’re on a specific diet, managing a deficiency, or just curious about your health. It’s time to go beyond calories and truly understand your food. * Apple Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ *
