A plain kitchen scale tells you a chicken breast weighs 180 grams; a nutrition scale tells you that is 297 calories and 56 grams of protein, logs it, and adds it to your day. The smart ones do it through a phone app with a database of a million foods and a barcode scanner; the old-school ones have the database printed in a booklet and a code pad on the scale itself. We ranked the smart nutrition and food scales in our home and kitchen catalog by weighing accuracy and capacity, the size and quality of the food database, whether the app syncs with Apple Health and Fitbit, how the scale behaves without the app, and what thousands of owners report after months of meal prep.
We have not weighed every meal on every one of these ourselves; the verdicts rest on the spec sheets and on the owner review history. Prices are not printed because they change daily; every button opens the live Amazon page. If you just need grams and ounces without the nutrition layer, our kitchen scales guide covers simpler models, and our countertop blenders guide pairs well with the protein-shake crowd this page attracts.
How we picked
- One-gram precision on every pick, with at least 11 pounds of capacity.
- A real food database. Either a large in-app database with search and barcode scanning, or a printed booklet with thousands of foods for the no-app pick.
- Health app sync. Most picks push to Apple Health and Fitbit; the ones that do not are noted.
- Works without the phone. Every scale here still weighs in grams and ounces with the app closed, and three show nutrition on the scale itself.
- Owner feedback from a few hundred to more than six thousand reviews, with app complaints weighed heavily because the app is the product.
The picks
RENPHO Smart Food Scale with Nutritional Calculator, Bluetooth App, Black

RENPHO’s scale is the one most people end up with, and with about 6,600 owner reviews and a strong owner rating it has earned the position. It weighs from 1 gram to 10 kilograms in 1-gram steps across five units, which is twice the capacity of most nutrition scales and enough for a full mixing bowl of batter, and its four sensors give consistent readings across the platform. The Renpho Health app holds the USDA food database, lets you add custom foods, logs meals by day and syncs with Apple Health; if you already own a Renpho body scale it all lives in one place. The scale itself shows weight only, so you are always looking at the phone for calories, and it runs on batteries rather than a rechargeable cell. Search for packaged brand-name items is the recurring gripe. For general meal prep and weight tracking it is the sensible default.
- About 6,600 owner reviews with a strong owner rating
- Double the capacity of most nutrition scales at 22 lb
- USDA food database with custom entries
- Compact, and the Renpho app also runs their body scales
- Nutrition shows in the app only, not on the scale
- Runs on replaceable batteries
- Database search can be fiddly for brand-name foods
Lepulse Smart Food Scale with Nutritional Calculator, Digital Kitchen Scale

The Lepulse fixes the main complaint about app-only scales: its color TFT screen shows weight, calories, protein, carbs and fat right on the scale, and a built-in library of 999 common foods means it works with the phone in a drawer. Pair it with the Fitdays app and you get a database of more than a million foods, 24 tracked nutrients, daily reports and automatic sync to Apple Health and Fitbit, with intake targets that adjust as you go. It weighs from 2 grams to 5 kilograms in 1-gram steps on a stainless platform with touch buttons. About 4,450 owners give it a strong owner rating and the screen is what they praise. The compromises are a 5-kilogram limit, touch controls that a damp finger can trigger, and the slow scroll through the offline list. For daily macro tracking it is the most convenient scale here.
- About 4,450 owner reviews with a strong owner rating
- Color screen shows macros without opening the phone
- Offline mode with 999 built-in foods
- Tracks 24 nutrients and syncs with Apple Health and Fitbit
- 5 kg capacity, half the RENPHO
- Touch controls can be triggered by a wet finger
- Navigating the offline food list on a small screen is slow

This is the value pick: a 1-gram, 5-kilogram scale with a bright LED display, USB-C charging and an app that pairs over Bluetooth to a database of more than a million foods, then saves every weigh-in into daily, weekly and monthly reports. It handles five units, including separate milliliter modes for water and milk, and the display is bright enough to read beside a sunny window. About 2,200 owners give it a strong owner rating, with the rechargeable battery and the price the usual reasons. It is an app-only scale, so calories live on the phone, and the brand is less established than RENPHO or Cosori if long-term app support worries you. The water and milk modes catch out new owners, so check the icon before pouring. For a first nutrition scale for keto, calorie-deficit or Weight Watchers tracking, it does the job for less.
- About 2,200 owner reviews with a strong owner rating
- Rechargeable over USB-C, no batteries
- Bright LED display readable in any light
- Million-food database and long-term trend reports
- Nutrition shows in the app only
- Less-known brand than RENPHO or Cosori
- Milk and water ml modes are easy to mix up
Ultrean Smart Food Scale with Nutritional Calculator, Kitchen Scale for Weight Loss, Food Weight Scale with App for Calorie & Macro Tracking, AI Scan, 33lb

Ultrean’s scale is the one for meal preppers who weigh a whole pot of chili rather than a single serving: it reads from 1 gram up to 15 kilograms, or 33 pounds, which no other scale here approaches, on a slim tempered-glass platform under seven inches across. The NutriScale app scans barcodes, shows up to 20 nutrition facts per food from a database of millions, and produces daily, weekly and monthly reports with suggestions. Four sensors keep readings steady even when a heavy bowl sits off-center. About 880 owners give it one of the best ratings on the page. The maker notes barcode scanning is US-only for now, it runs on three AAA batteries rather than a rechargeable cell, and a big stockpot overhangs the small platform even though the weight is within range. For batch cooking it is the most capable scale on the list.
- 33-pound capacity, the highest here, for whole-recipe weighing
- Barcode scanner and 20 nutrition facts per food
- About 880 owner reviews with one of the best ratings on the page
- Thin tempered glass platform wipes clean
- Barcode scanning is US-only at the time of writing
- Three AAA batteries
- Small platform for such a high capacity
Greater Goods Perfect Portions Nutrition Food Scale for Carb Counting, Grey

Not everyone wants a phone in the kitchen, and the Greater Goods Perfect Portions is the scale for them. You find the food in the printed booklet, type its code on the scale, weigh the portion, and the display shows calories, protein, carbs, fat and sodium laid out like a nutrition label. Save and Total buttons let you weigh each ingredient of a recipe into the same bowl and read the total. The database covers 2,000 common foods with room for 99 custom entries, capacity is 11 pounds at 1-gram precision, and the tempered glass surface wipes clean. About 500 owners give it a strong owner rating, many of them diabetics counting carbs who value the speed of no pairing and no updates. The trade is scope: 2,000 foods is a fraction of an app database, codes take longer than a barcode, and nothing syncs anywhere. For carb counting without a screen, it is the clear pick.
- No app, account or phone needed; everything is on the scale
- Nutrition-label display is instantly familiar
- Save and Total functions build a whole meal
- About 500 owner reviews with a strong owner rating
- Looking up codes in a booklet is slower than scanning
- 2,000 foods is small next to a million-item app
- Does not sync with any health app
EILISON Smart Kitchen Scale,TFT Display Food Scale,Nutrition Calculator

EILISON built the scale around its screen: a large color TFT that shows calories, protein, fat and carbs for whichever food you select, with 50 slots for your own custom foods stored on the scale so your usual breakfast is two taps away with no phone. Pair the app over Bluetooth and you get 999 foods with 24 nutrients each and a record of your intake. About 440 owners give it a strong owner rating and the screen earns most of the praise. Two things hold it back. The maker states 5-gram accuracy, which is fine for a plate of food but coarser than the 1-gram scales here for small portions of oil or nuts, and the app database is a fraction of the million-food apps from RENPHO or Cosori. It is also the priciest pick. For a household that eats the same fifty things and wants them on a big screen, it is a well-made scale.
- Big, bright color display with calories and macros on the scale
- Fifty custom foods stored on-device for app-free use
- About 440 owner reviews with a strong owner rating
- Bluetooth app adds 999 foods and 24 nutrients
- Stated 5 g accuracy is coarser than the 1 g scales here
- App database is smaller than the million-food apps
- The most expensive scale on this page
Cosori Smart Food Scale with Nutritional Calculator, USB Rechargeable, 11lb

Cosori’s Nutrilens is the scale to buy for the software. The VeSync app is the same one that runs Cosori air fryers and Levoit purifiers, so it is maintained, stable and familiar, and on the scale side it offers a database of more than a million foods, 19 tracked nutrients, daily targets for calories and macros that update with your progress, and an AI camera scan that estimates a restaurant plate when the scale is at home. The hardware weighs from 3 grams to 5 kilograms in 1-gram steps across seven units and charges over USB. About 400 owners give it the highest rating on this page. It costs more than the RENPHO for similar hardware, the 3-gram minimum is slightly higher than rivals, and nutrition appears on the phone rather than the scale. If you want the app you will still be using in three years, this is it.
- About 400 owner reviews with the highest rating on this page
- VeSync app is mature and runs Cosori and Levoit appliances too
- AI scan estimates nutrition when eating out without the scale
- USB rechargeable
- Minimum weight is 3 g, a little higher than rivals
- Nutrition shows in the app, not on the scale
- Costs more than the RENPHO
Taylor 5340117 Smart Food Scale with Precision Hub App, Digital Kitchen Scale for Macro Tracking and Calorie Logging, 11 lb Capacity, Measures Grams, Ounces & Liquids, Batteries Included

Taylor has made kitchen scales for decades and its smart model is aimed at households rather than individuals: the Precision Hub app stores up to eight user profiles, so a couple and two teenagers can each log meals from one scale, and it tracks fiber, sugar, sodium, cholesterol and vitamins alongside the basic macros. A barcode scanner handles packaged food, mealtimes auto-load so breakfast logs itself as breakfast, and everything syncs to Apple Health and Fitbit. The scale weighs to 11 pounds with the usual gram and liquid units, batteries are included, and the auto-off stretches to nine minutes when paired, which stops the mid-recipe shutdowns owners complain about on other scales. About 370 owners give it a strong owner rating. It is not rechargeable and the nutrition lives in the app, but for a whole family tracking together it is the only scale here built for the job.
- Eight user profiles, the most of any scale here
- Barcode scanner and tracking of fiber, sugar, sodium and vitamins
- Nine-minute auto-off when paired, so it does not shut down mid-recipe
- About 370 owner reviews with a strong owner rating
- Batteries rather than rechargeable
- Nutrition shows in the app only
- Taylor app is newer than the Renpho or VeSync ecosystems

App scale or no-app scale?
App scales win on database size, a million foods against two thousand, and on barcode scanning, logging and health-app sync. Their weakness is dependence: if the maker stops updating the app, the nutrition features die with it, and every weigh-in means picking up the phone. The Greater Goods Perfect Portions and, partly, the Lepulse and EILISON answer that with nutrition shown on the scale itself. If you track every meal and already use Apple Health or Fitbit, buy an app scale from an established ecosystem such as RENPHO or Cosori. If you count carbs for a medical reason and want zero friction, buy the booklet scale.
Accuracy, capacity and units
All but one pick here weigh in 1-gram steps, which is what you need for oils, nuts and anything calorie-dense in small amounts; the EILISON states 5-gram accuracy and is better suited to full plates. Capacity ranges from 5 kilograms on the Lepulse, Cosori and EILISON to 10 on the RENPHO and 15 on the Ultrean, and only matters if you weigh whole pots or bowls of batter. Every scale offers grams, ounces and liquid milliliters, usually with separate water and milk modes because milk is denser; a tare button to zero the bowl is universal.
Syncing with Apple Health and Fitbit
RENPHO syncs with Apple Health; Lepulse and Taylor sync with both Apple Health and Fitbit; Cosori logs into VeSync, which can pass data onward. The budget Bluetooth scale and the Ultrean keep reports within their own apps. The Greater Goods scale does not sync at all. If a single dashboard of weight, steps and food matters to you, check the sync list before the hardware, because the scales themselves are more alike than their apps.
How does a smart nutrition scale know the calories in food?
You weigh the food and pick it from a database in the app or on the scale; the scale multiplies the nutrition per gram by the weight. App scales use databases of a million or more foods with barcode scanning. The Greater Goods scale uses a printed booklet of 2,000 foods with codes you type in.
Do nutrition scales work without a phone?
All of them weigh in grams and ounces without the app. For nutrition without a phone, choose the Greater Goods Perfect Portions, which shows calories and macros on its own display, or the Lepulse and EILISON, which store foods on the scale and show nutrition on a color screen.
Which food scale syncs with Apple Health?
RENPHO, Lepulse and Taylor sync with Apple Health; Lepulse and Taylor also sync with Fitbit. Cosori logs into the VeSync app. The Greater Goods booklet scale has no sync.
How accurate are smart food scales?
Most picks here weigh in 1-gram increments from a minimum of 1 to 3 grams, which is accurate enough for oils and nuts. The EILISON states 5-gram accuracy, better suited to whole plates. Place the scale on a hard, level surface and tare the container for the best readings.
Can more than one person use the same nutrition scale?
Yes, if the app supports profiles. The Taylor stores up to eight users; RENPHO, Cosori and Lepulse support multiple accounts through their apps. The Greater Goods scale has no profiles, so each person totals their own plate.
