About this app

Primo Scale is an AI weight and size estimator. Photograph food, coffee, coins, jewellery or a parcel, and the AI estimates the likely grams, the dimensions, the number of items, or the calories.

IMPORTANT: this is not a physical scale. Your phone has no weight sensor, so Primo Scale never weighs anything. It recognizes the object, then estimates a likely gram range from its size and from reference data. Every figure is an informed estimate. When an exact number matters, use a calibrated scale.

HOW IT WORKS
- Point the camera at food or an object and take one photo
- The AI identifies what it is
- It draws on reference data, including the USDA FoodData Central database for food
- It estimates a likely gram range from visual size cues

Every result is shown as a range, never as a single certain number.

FOUR MODES, ONE APP
FOOD GRAM AI: estimate grams of food from a photo
- Grams, ounces, or pounds for ingredients, portions, and packaged food
- Built for baking, coffee, spices, meal prep, and portion awareness
- A gram estimator for the moments when no kitchen scale is at hand
- Works as an AI digital scale estimator, not as a scale

TAPE MEASURE: AI ruler and dimension estimator
- Estimate width, height, and depth of an object from a photo
- Switch between metric and imperial units
- Approximate only

OBJECT COUNTER: count from one photo
- Count coins, pills, nuts, bolts, or similar repeated items
- Useful for inventory, stock, crafts, and DIY
- Based on image recognition, so it can miscount

CALORIE ESTIMATOR: AI food scanner
- Identify a meal and get approximate calories plus macros
- Protein, fat, carbs, and fiber, backed by the USDA nutrition database
- Estimates only, not medical or nutritional advice

WHAT PEOPLE ESTIMATE MOST
- Rice, pasta, oats, and flour when following a recipe
- Chicken, fish, and meat portions before cooking
- Coffee beans and ground coffee for a pour over
- Cheese, nuts, and snacks for a quick calorie check
- Sugar, butter, and cocoa for baking
- Fruit and vegetables for meal prep
- Coins, rings, and small gold or silver items
- Letters and parcels before a trip to the post office

Point, shoot, and read the estimated range. No setup, no reference card, no extra hardware.

WHO IT IS FOR
- Home cooks and bakers estimating grams of food without a digital kitchen scale
- Diet and fitness users checking food portions and calories from a photo
- Jewelry sellers and hobbyists who want a quick gram estimate
- Home shippers who want a rough size and weight estimate before posting
- Makers, crafters, and resin artists working with small parts
- Small businesses counting stock and checking dimensions

WHY PRIMO SCALE
- A food gram estimator first, an object estimator second
- Every estimate is a range, never a single certain figure
- Powered by Google Gemini
- No calibration card or physical reference object needed
- Metric and imperial units supported
- Local history, private by default

A NOTE ON ACCURACY
Primo Scale is an estimation tool, not a measuring instrument. It is not a physical scale, it has no load cell, and it does not use phone sensors to weigh. Think of it as a digital scale style gram estimator: handy when no scale is around, and honest about being approximate. For anything critical, medical, professional, or commercial, use a certified physical scale.

not to terrible, it could have a more accurate reading, if this is a ai doing the reading, should be able to scan and nearly act as if it's picking up the item l and weighing it, shall it then be able to determine by the side what all it can meaeure out to be. once a update is in session and aingers used correctly this could be a very reliable scale.

Thanks for the detailed note on scan accuracy. Improving the AI weight estimate is exactly what we're working on now. If a specific item reads off, email info@techprimo.ai and we'll tune it.

Didn't allow certain things to be weighed.Like rock candy said it was a unknown crystal substance.But then removed a piece from the bag and said it was a rock crystal a fragment.It was what children had made from a string put into a heavy sugar water.After several days it clings to the string in crystals.Forming different shapes called rock 🍬 candy Simply wanted the weight.

Thanks for the detail, that's a real gap. Weight mode identifies the object first, and homemade rock candy on a string isn't something it knows, so it guessed at a crystal. Letting you skip identification when you only want a weight is something we're looking at. Sorry it got in the way.
