Disadvantages and Limitations

Requires Bluetooth Connection for Full Features: While the scale measures weight standalone, accessing nutritional information requires pairing with a smartphone via Bluetooth[3][6].
Database Limitations for Specialty Foods: Although the food database is extensive, some specialty, regional, or newly released food items may not be in the USDA database, requiring custom entry[2].
App Dependency: Full functionality relies on having a compatible Android or iOS device and the VeSync app installed[3][6].
Food Selection Variability: For items with multiple serving size options (small, medium, large), users must estimate the correct size, which may not provide exact nutritional data without precise measurement[6].
Battery Replacement Needed: While batteries are pre-installed, users will need to purchase replacement AAA batteries over time[1][4].

Customer Reviews and User Feedback

Users consistently praise the Etekcity Smart Nutrition Scale ESN90 for transforming how they approach nutrition tracking and meal preparation[2][5][6]. Reviewers highlight that the scale is "a game changer for healthy eating," combining the functionality of a traditional kitchen scale with intelligent nutritional analysis[2]. Many users appreciate that the scale "measures not only the weight of your food but also provides nutritional information for a wide variety of ingredients," making it particularly valuable for those tracking calories, macronutrients, or following specific diets like keto[2][5][6].

Common praise includes the ease of use: "Very easy to set up once you insert triple A batteries," and the accuracy of measurements, with one reviewer noting that volume measurements were "only off by 3" milliliters when tested against a standard measuring cup[5]. Users particularly value the ability to instantly access nutritional data by selecting food items in the app, eliminating guesswork compared to traditional calorie-counting methods that rely on portion size estimates[6].

The primary concern mentioned by users involves the necessity of pairing with a smartphone to access full nutritional features, as the scale alone displays only weight measurements[3][6]. Additionally, some users note that for foods with multiple serving size options, selecting the correct size requires estimation rather than precise measurement[6]. Despite these minor limitations, reviewers recommend the ESN90 smart nutrition scale to anyone serious about nutrition tracking, fitness goals, or dietary management, valuing it as an investment in health and wellness that delivers genuine utility beyond standard kitchen scales.

How to Use the Etekcity ESN90 Smart Nutrition Scale

Basic Weight Measurement

To use the Etekcity Smart Nutrition Scale ESN90 for simple weight measurement, first insert the three 1.5V AAA batteries that come pre-installed[1][4]. Press the power button to turn on the scale, then press the unit selection button to choose your desired measurement unit: ounces, pounds, grams, or milliliters[4][5]. Gently place your food item on the weighing platform, and the digital display will show the weight immediately[4].

Tare Function for Container Measurement

To measure ingredients in a container, first place the empty container on the scale[4]. Press the power/tare button to zero out the container's weight[4]. The display will reset to show "0." Now place your liquid or ingredients in the container, and the scale will measure only the contents without including the container weight[4]. This feature simplifies multi-ingredient cooking by allowing sequential measurement of each ingredient without removing the container[2].

Accessing Nutritional Information

For complete nutritional analysis, download the VeSync app on your Android or iOS device and enable Bluetooth on your phone[3][6]. Turn on the ESN90 nutrition scale and pair it with the app via Bluetooth[2]. Place your food item on the scale to obtain its weight measurement[6]. In the app, search for the corresponding food item from the database of over 8,000 foods[2][3]. Once selected, the scale will display detailed nutritional information including calories, carbohydrates, protein, fat, cholesterol, and 14 additional nutrition facts[1][7]. The app also displays this information on your smartphone screen[6].

Creating Custom Food Entries

The VeSync app allows you to create custom entries for unique recipes or foods not in the standard database[2]. This flexibility ensures you can track any food item, making the Etekcity Smart Nutrition Scale ESN90 adaptable to diverse dietary needs and personal recipes.
