Say what you ate the way you'd tell a friend, and get honest calories and macros against your budget.
Describe what you ate the way you'd tell a friend — "two eggs on toast, a flat white" — and get honest calories and macros against a budget you set together, every day. Nothing to weigh, no barcodes, no app to open: say the meal in passing and it lands on the log with an estimate that says it is one. The board keeps the day's arc against your budget, the macro split, the week day by day, the protein line and which days you logged; the evening close asks once about a meal you skipped mentioning and gives you the day in one line of arithmetic — never a verdict. Set the budget from numbers you already use, or let it work one out and show its method. If you also keep Weight & Body, the budget reads your goal and the close puts the smoothed weight beside your calorie balance. A photo of the plate works too, and its estimate says what it assumed. Fibre, water, caffeine and alcohol go on the same line when you mention them, and so does the time, so the board can show the day's first and last meal beside an eating window if you keep one. The meals you have again and again are kept as usual meals and logged from the board with a tap; a recipe is worked out from its ingredients, each figure with its source; and if you keep Meals & Groceries, the week's plan is added up against the budget when you ask. Ask for the budget to be worked out again as your weight moves and the method is shown again. It is all arithmetic: it never says what fits the rest of the day, and it gives no advice on what to eat.
1 agent, 1 routine, 1 dashboard, 3 datasets, 4 skills. Installing ends with Meet Fern — a short conversation sets it up, and everything can be retimed or paused after.

The crew
Fern
Keeps honest estimates, and keeps its opinions to itself.
Plain, unhurried, honest about what an estimate is.
What else it installs
One line per meal, with an estimate that says it is one.
The budget and the macros you are working to, and how they were arrived at.
The meals you have again and again, and recipes worked out, each with its figures.
"Two eggs on toast and a flat white" — that is the whole interaction.
A calorie budget and macros, with the method shown — or the numbers you already use.
The meals you have again and again, kept with their figures, and a recipe worked out from its ingredients with a source for every figure.
The week's meal plan added up against your budget, day by day, when you ask.
A usual meal with a tap, the day against your budget, the macro split, the week, and the days you logged.
Every evening — asks once about a meal you skipped, then the day in one line.

A kit earns its place when it changes what you look at and what you say, not when it is installed. This is the rhythm that makes it pay.
Nothing here is fixed. The pieces are ordinary agents, routines, datasets and dashboards, so anything you know about shaping those applies. Retire whatever earns nothing.
Say any of these in chat, or edit them on the kit’s page in the app.
Installing starts a short setup conversation — not a form. Answer roughly, correct later.
Watch the first pass, then tell it what you would have done differently — that correction teaches it more than any setup could.
Learning, preferences and run costs work the same in every kit — so they are covered once, in the Kits guide.
Install it, run it once against something that already happened, and see whether what comes back sounds like you.
