Photograph the plate. A few hours later, one question: how did it sit? Energy, focus, mood and appetite, filed next to the meal. Every number can be switched off. Every food app tells you what you ate. Plateknow also keeps what happened next. Photograph the plate. You get the dish named, an honest range instead of a confident number, and one tap to correct it. A few hours later the app asks one short question — how did that sit? — and files the answer next to the meal. That pair, the plate and what followed it, is the whole product. Enough of them and the app starts telling you what it noticed: on the days you logged fried, digestion read uneasier later on. On the days you logged coffee, focus read sharper in the first three hours. Your own readings, against your own average, never against anybody else's. WHAT PEOPLE USE IT FOR Finding a way of eating that leaves you focused and comfortable. Understanding what the body is asking for — and the eating patterns behind better training and performance. THE NUMBER IS OPTIONAL One switch removes every calorie, gram and percentage from every screen. Nothing else goes with it: the photographs, the dish names, the corrections, the portions and the check-ins all stay, and the app never asks you to turn them back on. Turn the numbers off in a normal calorie tracker and there is nothing left. Turn them off here and what remains is the point. NOTHING THAT CAN GO DOWN No streak. No daily deficit. No word for going over. The only counters in this app are ones that rise — plates photographed, distinct dishes, weeks logged. A day you did not open it is a day you did not open it. AN HONEST RANGE A photograph is not a measurement, so the estimate is shown as a band rather than a single confident figure. Correcting a name takes one tap and is the most useful thing you can do — it fixes the meal, and the tags the patterns are built from. COOK IT AGAIN The log points forwards too. Dishes you already eat, with the ingredients you were already served, your own photograph, and the one line a recipe app cannot print: what your own record says happened the last few times you had it. WHAT'S IN IT - Photo capture with the plate cut out on your phone - Energy, macros, appetite and ingredients, each a tap deep - Post-meal check-ins on energy, focus, mood, digestion and fullness - Weekly patterns, and longer horizons with Pro - Body photos that never leave the device - Nutrition label scanning, read on-device - Search your own log by food, by feeling, or by what was in it - iCloud sync in your own private database - Ten free AI estimates a day, for ever PRIVACY Your meals sync through your own iCloud, in a private database we cannot read. Body photographs never leave the phone at all. There is no account and no password. When an estimate is made, what is sent is the cut-out of the food — never the whole photograph, never your face, never where you were. Estimates only. Plateknow does not diagnose anything and is not a medical device. SUBSCRIPTION Plateknow Premium is an auto-renewing subscription, offered monthly and yearly.
