Read full description

HAKARI is a nutrition tracking app built for serious athletes and bodybuilders. Unlike general diet apps, HAKARI is purpose-built for those who need precise macro tracking, bulk and cut cycle management, and data that stays on their device. [ Why HAKARI ] Gram-level precision Logging "one serving" or "about 200g" won't cut it. HAKARI tracks every gram, calculating your calories and PFC (protein, fat, carbs) in real time as you log. Bulk, Cut & Maintenance Cycle Management Switch between five phases - lean bulk, aggressive bulk, moderate cut, aggressive cut, and maintenance - and let HAKARI automatically recalculate your optimal macro targets for each phase. Adaptive Calorie Adjustment HAKARI compares your actual weight trend against your goal and suggests calorie adjustments when needed. Stay on track without second-guessing your numbers. 1,081 Foods Bundled - No Internet Required A built-in food database based on the Japanese Standard Tables of Food Composition. Search and log entirely offline. Custom foods are unlimited. 100% Local, 100% Private Your meal logs, weight data, and body measurements never leave your device. No server. No account required. [ Features ] Meal Logging - Barcode scanner for fast entry - One-tap logging from recents and favorites - Meal templates for your go-to combinations - Four meal types: breakfast, lunch, dinner, snacks Nutrition Tracking - Real-time calorie and PFC calculation - Remaining vs. target display at a glance - BMR and TDEE auto-calculation via Mifflin-St Jeor formula - Macro targets auto-set from your profile Cycle Management - Five phases: lean bulk, aggressive bulk, moderate cut, aggressive cut, maintenance - Set start date, target end date, and weekly weight change goal - Adaptive calorie adjustment suggestions Body Tracking - Log weight and body fat percentage - Measure waist, arms, and thighs - 7-day moving average graph to cut through daily fluctuation - Period options: 7, 14, 30, and 90 days Statistics - PFC compliance rate (days on target / total days) - Calorie trend graph - Daily stacked PFC bar chart Data Management - CSV export for meal logs and weight history - Full data reset - Privacy policy [ Who Is HAKARI For? ] - Competitive bodybuilders, physique athletes, and serious lifters - Anyone running structured bulk and cut cycles - People who weigh their food and want precision tracking - Users who care about data privacy and hate ads - Anyone tired of diet apps that treat them like a beginner [ About HAKARI ] The name comes from the Japanese word for "scale" - a tool of precision. That philosophy runs through every feature. One-time purchase with no subscription. Pay once, use forever. No recurring charges, no paywalls that reset. Designed with privacy first. Your food logs, weight, and measurements are stored only on your device and are never transmitted to any server. [ Important Notes ] - HAKARI is a tool to support healthy training habits - It does not provide medical advice - Consult a healthcare professional before making extreme dietary changes - The bundled food database is based on the Japanese Standard Tables of Food Composition. Food composition data for the US, UK, and other regions is not yet available. Support for additional regions is planned for a future update.
