Yes. Photograph your plate and Sayved reads the food, estimates the portion, and returns calories, protein, carbs and fat in a few seconds. Every number comes with a range and a confidence, so a guess never passes for a measurement.
Sayved turns a photo of a meal into a logged entry with calories and macros. You do not search a database, pick a portion size, or scroll a list of near-identical foods. You take the picture, and a few seconds later the meal is in your diary as an estimate you can read, correct and ask about later.
You tap the one floating button that sits over every screen and choose photo. The camera opens straight away. Take the shot, add a second one if the dish is spread out, and save. Before it is saved you see a short review screen, so a blurry or accidental picture does not end up in your log.
On your phone the photo is shrunk first. Food photos are reduced to roughly 640 pixels on the long edge, which is plenty to recognise a plate and keeps the upload small. That downscaled copy, not the original, is what goes to an AI model for reading. The model returns the foods it can see, a judgment about the portion, and calories plus protein, carbohydrate and fat. Sayved files this as a meal entry. You never choose the category: it works out that a plate of food is a meal.
The whole capture is meant to take under ten seconds. If the reading cannot be confident, for example because the plate is half out of frame, the entry is saved anyway with a lower confidence. Sayved never stops you with a question when you are standing in a kitchen holding a fork.
Honest answer: approximate. A photo shows the surface of a meal. It does not show how much oil went in the pan, whether the yoghurt was full-fat, or how deep the pasta bowl is. Any app claiming exact calories from a picture is promising something a camera cannot deliver.
So Sayved is built around uncertainty rather than around hiding it. Each estimate is stored as a point value, a low and high bound, and a confidence level. In the entry you will see something like “about 610 kcal, range 500 to 730, medium confidence”. A simple plate of grilled fish and vegetables gets a narrow range. A casserole under melted cheese gets a wide one, because that is the truth.
What you can rely on is consistency. The same plate tends to read the same way next week as it does today, which is what makes a diary useful over time. Totals and charts are built from those estimates, and they carry the ranges with them. They describe what you recorded. They are not a lab result.
Yes, and this is a core rule of the app. Every derived value is editable: the food names, the portion, the calories, each macro. If you know the soup was 350 kcal because you read the carton, type 350.
Your edit does not overwrite the original. Sayved keeps the model’s reading and your correction as two separate things, and shows yours. That matters for two reasons. First, nothing is silently lost, so you can always see what the app first thought. Second, it keeps the record honest: a number you typed is a number you chose, and a number the model estimated is labelled as an estimate.
If you often have a plate where the app runs high or low, correcting it a few times is a quick way to see the pattern. The app does not nag you to do so, and it does not volunteer conclusions. You decide how much to fix.
Some meals do not fit in one frame: a main dish and a side, or a plate next to the wrapper it came from. You can attach more than one photo to a single meal and review them together before saving. They become one entry, not several, so your totals do not double count.
If you photograph packaging, Sayved treats it differently from a plate, because printed numbers are far more reliable than a portion judged by eye. That case has its own page: see the nutrition label scanner.
Your diary lives on your phone, in a local database. There is no account, and Sayved does not ask for your name or email. When you photograph a meal, a downscaled copy of the picture is sent to an AI model to be read, with no name, email or account attached. Nothing is stored on Sayved’s servers, and the original photo never leaves the device. Voice is handled separately: speech is turned into text on the phone, and audio is never uploaded. The full explanation is on the privacy page.
The entry is only the start. Meals feed the Today view, the weekly and monthly reports, and the food charts, where you can see energy and macros as the plain totals of what you recorded. They also feed Ask, where you can write a question such as “what did I eat the day before the headache?” and get an answer built from your own entries. There is more on that in health charts and reports.
None of this turns into a verdict. There is no calorie goal to hit, no streak to keep, and no colour that says a day was good or bad. The photo is there to save you effort, not to score you.
Photo reading is included in the 14-day free trial, then Sayved Pro costs $2.99 a month. If you stop, everything you already logged stays readable, searchable and exportable, free, forever. Typing entries keeps working as well. See pricing for the detail, or read how a food diary works end to end in Sayved.
“Photo of a bowl of rice with grilled chicken and cucumber”
Illustrative entry. Estimates always show their range.
No photo estimate is exact, and Sayved does not claim otherwise. It aims to read the same plate the same way each time, and it shows a range and a confidence so you can see how much room there is in the number.
Tap it and type the right figure. The corrected value is stored separately from the model's original, so your record shows both.
The original stays on your phone. To read the meal, a downscaled copy is sent to an AI model with no name, email or account attached, and nothing is kept on our servers.
Yes. You can say it, type it, or photograph a nutrition label. The same entry comes out whichever way you capture it.
No. Sayved describes what you ate and never grades it. There are no goals, scores or red days.
Photograph a nutrition label and Sayved scales the printed numbers to the amount you ate, so the total comes from the pack, not a guess at a portion.
A voice food diary that turns "two eggs and toast" into a logged meal with calories and macros. Speech stays on your phone; audio is never uploaded.
Log protein, carbs and fat by photo, voice or nutrition label. Sayved estimates each with a range and shows your split. Every number is editable.
A food diary app where you snap a plate or say what you ate. Sayved saves the meal with a calorie and macro range, and you can edit any number.
Sayved turns what you log into food, sleep, mood and symptom charts for a week to all time. Averages use logged days only, with no grades or red days.
Free for 14 days, then $2.99 a month. Everything you've logged stays yours, readable and free, forever.
