Protocol is an adaptive fitness system for nutrition, training, fasting, body composition, and accountability. Protocol exists to remove excuses by replacing motivation with structure. It treats the body as a system that adapts to conditions, not emotions. The app is not a motivator, diary, or game. It is a compliance engine that records reality, reinforces constraints, and helps you operate the system long enough for results to compound. Scan meals. Generate workouts. Track lifts, macros, fasting, sleep, steps, weight, and weekly progress in one system that learns how you eat, move, train, and recover. Built for consistency over motivation, Protocol gives you structure without guilt mechanics, streak pressure, or noisy dashboards. Just clear targets, adaptive feedback, and tools that keep your plan moving. MEAL LOGGING Log food with a photo, text, barcode, or saved meal. Protocol estimates calories and macros in seconds, then lets you edit every entry by ingredient or macro. Save meal preps, relog common meals, and use verified local food data for faster, cleaner tracking. TRAINING Build custom training plans across strength, hypertrophy, conditioning, endurance, and performance. Choose 2–7 day splits, target specific muscle groups, log sets and rest times, swap exercises, save templates, and track progressive overload, volume, density, and personal records over time. BODY + HEALTH DATA With Apple Health permission, Protocol uses steps, workouts, weight, sleep, and activity data to help estimate your real energy needs. Track weight trends, body composition scans, compliance patterns, and weekly changes without turning your health into a scorecard. AI COACH Protocol’s AI coach uses your logged nutrition, training, compliance, and progress context to give more relevant answers. Ask questions, generate workouts, review patterns, and adjust your plan with guidance based on your actual data, not generic advice. HUMAN COACHING Sentinel connects you with a real coach inside Protocol. Your coach can review your training, nutrition, and body composition context, adjust programming, update macros, and communicate through built-in chat. No scattered spreadsheets. No third-party messaging. One system. BUILT TO KEEP YOU ON TRACK Daily reviews take seconds. Weekly audits surface patterns you might miss. Intelligent reminders help redirect your attention when meals, training, fasting, or check-ins fall behind. Protocol is not just a tracker. It is a structured operating system for staying consistent.
