Stop guessing. Stop starving. Stop restarting on Monday. Most nutrition apps hand you a calorie target and wish you luck — then leave you to do all the work. Meal Engine is different. It's a real AI coach that adapts to you, your body, and your real life. And it works the way YOU want. OPTION 1: Full Meal Plan Coaching (Everything done for you) → Get a personalised 7-day meal plan built around your goals, training, and the foods you actually like. Every meal, every day — with recipes and a shopping list that writes itself. Add a snack or eat out, and your plan rebalances automatically so you stay on track. OPTION 2: Macro Coaching (Eat freely with guidance) → Get your perfect calorie and macro targets, then log however you like — snap a photo of your plate, say what you ate, or scan a barcode. The AI does the rest: every food, portion, and macro, in seconds. *Either way, you get the part no other app gives you — which is an actual coach. WHY MEAL ENGINE IS DIFFERENT Talk to it like a real coach → Ask anything out loud, while you cook, drive or wind down. Why did my macros change? What should I eat tonight? It knows your numbers, so you get a real answer instead of a search result. No typing. No waiting. A coach that actually coaches → Every week it reviews your real data — your meals, weight, and progress — then adjusts your plan and targets. The kind of personalised coaching that normally costs hundreds a month. Eat what you love, stay on track → Add the chocolate. Order the pizza. Your plan quietly rebalances around it so one treat never derails your day. Your day, on your Lock Screen → Calories left, macros, and your next meal — live on your Lock Screen and Dynamic Island. Tick a meal off without opening the app. It knows your body (including your cycle) → For women, it tracks your cycle and explains the bloating, cravings, and scale jumps — and what actually helps. See the full picture → Macros, micronutrients, steps, and weekly trends — synced with Apple Health. Way more than just calories. WHO IT'S FOR: • Anyone who wants to know exactly what to eat — without the math • People who want real coaching, not just another tracker • Busy people who need something that fits real life • Anyone who's tried everything and wants a plan that adapts • People who want to lose fat without giving up the foods they love WHAT'S INCLUDED → The Engine — your 24/7 AI coach, by voice or text → Personalised macro & calorie targets, adjusted weekly → Done-for-you 7-day meal plans with recipes & shopping lists → AI food logging — photo, voice, barcode & nutrition label → Weekly check-ins that review your data and rebuild your plan → Smart food swaps with automatic rebalancing → Live Lock Screen & home screen widgets → Cycle-aware coaching for women → Micronutrient tracking + Apple Health sync → All diets — omnivore, vegetarian, vegan, pescatarian, keto, plant-based → Allergen-aware — filters gluten, dairy, nuts, soy, eggs, fish, shellfish → Available in English, Spanish, Portuguese, German, Italian & French REQUIRES A SUBSCRIPTION Meal Engine requires a paid subscription to access meal plans, macro & calorie coaching, AI food logging, weekly check-ins, and The Engine.
