One loop, repeated: photograph a plate, confirm what it is, and the week’s figures move. Everything below happens on the phone, and nothing is recorded until you say so.
1 · Photograph the plate
The app opens on the camera, pointed at the food rather than at a menu. Frame the plate in the middle and take the shot. Recognition runs on the device — the photo is not uploaded, and it is not added to your log either; it exists only until you have finished with it.
If the middle of the frame isn’t food, the app says so rather than guessing, and takes you straight to describing the dish yourself.
2 · Confirm what it is
Five dishes are proposed, each with its main ingredients underneath so two lookalikes can be told apart. Tap the one that matches. More dishes adds five more below the first five, and Not found? Add yours lets you name the dish and type its ingredients — it is then scored from your words and nothing else.
Then the portion: Small, Normal, Large or Double. Four coarse steps, not grams, because a photograph cannot recover grams and the app will not pretend otherwise.
Recognition proposes; you decide. Nothing reaches your log until you confirm it.
3 · Read what the plate moved
The receipt that follows is not a score for the meal — no single plate has one. It lists what the plate moved in each pattern you have on: the components it fed, and the ones it counted against. A stir-fry might read +2 against one rubric and +1 −1 against another. A tap on that line opens a page explaining what those figures are counting.
4 · The week is the score
Home carries the figure that matters: your last seven days, weighed against each pattern, with how many of those days you logged printed under it. The window rolls — a plate ages out on the day it was logged — so the score is re-derived every time you look at it rather than stored.
Each pattern prints on its own published scale by default; Profile → Scores rescales all four to 0–10 if you would rather compare them at a glance. How this is scored at the foot of Home explains the arithmetic, including why a partly logged day pulls the week down.
5 · Ask a score why
Tap any of the four rows and you get that rubric’s components, each with the rule it was scored against and where your week landed against it. Nothing is a bare number: if a figure is low, the line that made it low is on the same screen. Where a measurement was never taken, the rubric says so and leaves the plate out rather than scoring you on a number nobody has.
Four patterns, and why they disagree
MIND, DASH, Mediterranean and HEI-2020 are published instruments, each with its own definition of a good week. A week that does well on one and poorly on another is telling you something a single number cannot. Profile → Dietary patterns switches any of them off, and off means gone from Home rather than greyed out.
Fixing and keeping the log
Logs holds every plate by day, and tapping one reopens its receipt. Logged the wrong dish? Swipe the row and Remove — one plate at a time, which is how the mistake is usually made.
Profile → Your log → Backup writes the whole log and your settings to a file you can keep in Files or iCloud Drive and read back on another phone. There is no account, so there is nothing to lock you out — and nothing that copies itself to a new phone on its own.
The first seven days
The trial is seven days and it starts when you log your first plate, not when you install — the camera, the dish list, describing your own and the receipt all work before the clock starts. After that it is a single purchase. No subscription, nothing renews.
