Eat well and reach your goal, a week at a time.

• Chat like you'd text a friend.

  He reads your week, your targets and what you've logged, and answers in a sentence or two, never a lecture. Try the three below.

• Or just call him.

  Tap Call and talk it through. Your speech is turned into words on your iPhone itself, so the audio never leaves the phone and nothing is kept. Interrupt him any time; he stops and listens.

• He talks back, and his face follows.

  Replies can be read aloud in the Chief's voice while his animated head listens, thinks and speaks with you. The one on this page is the real thing: move your pointer and he'll follow it.

He never claims a change he didn't make. What the app records is written by code from what actually happened, not from his say-so; a whole day, asked for by name, is planned by code too.

• Every plate comes from a real catalog.

  Every meal is built from a closed catalog of 266 ready plates across 23 cuisines, each food priced per gram from USDA nutrient data. The Chief can't invent a dish with invented numbers.

• Vitamins and minerals count too.

  Each day lands in your calorie band with your protein and fibre floors met, and the week is checked against 20 vitamins and minerals. What food can't close, he names plainly and suggests a fortified food or a supplement. Nothing is added unless you say yes.

• Allergies and never-eats are enforced in code.

  Peanut allergy, coeliac, vegan, no pork: every write is checked against your limits before it lands, down to the method steps. A plate that says “peanuts on top” is never offered to you, whatever the model suggests.

• A shopping list you can carry.

  A few proteins shared across the week, variety from cuisine and preparation rather than from buying more. The list is grouped by aisle, counts eggs and fruit in pieces, ticks survive a relaunch, and it exports with one tap.

• Familiar in the morning, yours at night.

  Breakfasts you'd recognise: porridge, eggs on toast, overnight oats. Lunches and dinners from the cuisines you like, nothing two days running, and “loose” (variety first) or “strict” (nutrients first) is your call.

• From any web page.

  Find recipes opens a Google search inside the app. Pick a page, tap Use this recipe, and the Chief reads it, works out its calories and sizes one serving to the meal it is for.

• From a photo.

  A cookbook page, a recipe card, a screenshot. Snap it and the recipe is copied out, priced and sized the same way. He reads recipes, not plates: no guessing calories from a picture of your dinner.

• Your own, by name.

  Any dish you name goes on the plan, priced from its ingredients and checked against your limits like everything else. Save it to your library, and it comes back most-used first.

• Cook mode.

  Every recipe is grams plus numbered steps. Tap Cook and the screen walks you through one step at a time and stays awake. Each ingredient line shows exactly what it was priced from.

• Keep the log, earn the rank.

  A day goes in the ship's log when every planned meal is logged. Each Monday brings an anchor that covers one missed day. Miss one with no anchor and the count goes back to your rank's floor, never to zero, and a rank once earned is yours for good.

• Apple Health, read when needed.

  Weigh-ins, calories burned, steps and workouts come in from Apple Health on demand and are never stored. Tell the Chief a weight and it goes to Health too. One switch turns all of it off.

• A projection that's honest.

  After two weigh-ins, your projected goal date comes from a line fitted through your last fourteen, so one heavy weekend doesn't move the finish line. Intake and burn charts run over the whole goal, not one week.

• One quiet nudge, if you want it.

  An evening reminder, only when a meal is still unlogged. Change the time or turn it off by asking the Chief.

First Mate at 14 days in the log. Once earned it's yours for good: a missed day with no anchor takes the count back to 14, where First Mate began, never below.
