How Food to Mind works

Three steps, and then the part people skip: a food log only means something when you read it alongside everything else that happened that day.

Photograph the meal before you eat it. An estimated forecast comes back in about five seconds — a prompt to pay attention, not a measurement. You can log a meal without a photo, and the app still works if you never grant camera access at all.
About ninety minutes later the app asks where your mind is: mood, focus, mental clarity, plus any symptoms you want to tap. This is the half of the journal that is actually about you. The forecast is a guess; the check-in is data.
Once a handful of meals carry both a forecast and a check-in, the journal starts to repay reading. Look for the meals that keep appearing next to your clearest hours — not for a verdict.

When personalisation starts

After three or more completed check-ins, the app begins drawing on more of your own history when it builds a forecast. That is the entire meaning of “personal” here. It is not a claim that a pattern has been established, that a cause has been isolated, or that the app has learned which foods work for you. It means the estimate is using more of your own answers than it did on day one.

What else was going on

A meal is never the only input. Sleep, workload, stress, screen time, caffeine, when you ate, and how much you moved all shape how clear an afternoon feels. Food to Mind records none of that, which is exactly why it will not tell you a food caused anything. Read your own log with the rest of the day in view.

How much you slept, and how well.
Workload, deadlines, and how much of the day you spent sitting still.
Stress, and whatever else the day put in front of you.
Caffeine, alcohol, water, and when each of them happened.
Movement — a walk after lunch is not nothing.
Where you ate, how fast, and who with.

None of that is in your journal, so none of it can be ruled out. That is the honest limit of a food log, and it is worth knowing before you read one.

What it records, in full

The what a mental clarity log can and cannot show you page lists every field the app stores and every thing it deliberately leaves out. The FAQ answers the questions people ask first.
