Protocol is an adaptive fitness system for nutrition, training, fasting, body composition, and accountability. A Protocol Operator subscription is required to use the app.
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.
SUBSCRIPTION
Protocol is free to download. Using the app requires a Protocol Operator subscription, which unlocks every feature. Choose monthly or annual billing.
• Payment is charged to your Apple ID account when you confirm the purchase.

ONE PLAN. EVERYTHING INCLUDED.
Protocol is now a single Operator membership with every feature unlocked: meal scanning, the training engine, body scans, the AI coach, weekly audits, and nutrient tracking. There is no longer a free plan or free trial. If you already subscribe, nothing changes. If you were on the free plan, your data is still on your device, and subscribing or restoring a purchase picks up right where you left off.
MEAL SCANS
Your photo now appears inside the scan card while Protocol analyzes it. If a scan fails, you can retry or log the meal manually right from the card instead of starting over. The progress count is smoother too, and nutrient detail now comes through on photo scans.
WORKOUT LOGGING
Minimized a 1-Tap workout? Tap the live workout strip to jump back in. The exercise picker remembers the muscle group and region you used last, so a leg day no longer means picking LEGS for every station. Buttons across the logger are larger and easier to hit mid-set.
APPLE HEALTH
Protocol now asks only for the Health data it actually reads (steps, exercise minutes, sleep, energy, and heart rate) and no longer requests write access. Onboarding asks once instead of twice.
Also: smaller fixes and layout polish throughout.
