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.

Food is the one part of diabetes that still feels manual. Whether you are cooking at home, ordering takeaway, eating out, or trying something new on holiday — Bettie takes the guesswork out of carb counting so you can enjoy your meal, and the hours after. Subscription required for full access. Pricing is shown in the app before purchase. **Snap a photo. Get the carbs.** Take a photo of your plate and Bettie breaks down the carbs, protein, fat, and calories. It works with homecooked meals, restaurant plates, street food, packaged snacks — anything. You can also scan a barcode, photograph a receipt, or just describe what you are eating. **See how meals actually hit** Connect your CGM data and Bettie maps every meal to your glucose curve. Instead of guessing which meals work for you, you can actually see it. **Build your personal playbook** Over time, Bettie builds a picture of how you eat. Search your history for similar meals, compare glucose responses side by side, and spot the patterns that keep you in range. **Refine with a conversation** Not sure about the portion? Something you have never had before? Ask Bettie. The built-in assistant can refine estimates, pull up past meals, and give you context on your glucose trends. **Four ways to log. Zero friction.** - Photo / snap your plate - Barcode / scan packaged food - Receipt / photograph a receipt or menu - Text / describe it in your own words **Glucose insights that actually help** - See which meals keep you steady and which ones surprise you - Compare similar meals side by side - Track patterns and trends over time **Built for people who count carbs every meal** Bettie is not a diet app. It is built for people who count carbs all day, every day - at home, at work, eating out, or on holiday. The goal is to make food feel less like a maths problem and more like just eating. Terms of Use: https://bettie.app/terms
