Choosing between a Picooc and Xiaomi smart scale is not just a matter of price or design; the accuracy of your training program is a matter of performance; the functionality is a matter of long-term usability. Both brands belong to the Xiaomi ecosystem (Picooc is a sub-brand), but the approaches to implementing key features are radically different. For example, Xiaomi Smart Scale 2 synchronizes only with Mi Fit, while Picooc S3 Lite supports Apple Health and Google Fit – critical for iPhone owners.
In this article, we will analyze 8 key parameters: from measurement error (tests on 3 models) to compatibility with fitness bracelets and features of mobile applications. You will learn why the Picooc scale with 4 sensors is more accurate than Xiaomi with 2 sensors by 12-15% when measuring muscle mass, but lose in timing speed. And also examine the hidden “pitfalls” – for example, why Xiaomi Body Composition Scale 2 can show an inflated percentage of fat in athletes with developed muscles.
Measurement accuracy: laboratory tests and real-world data
The main criterion for smart scales is the error of measurement. We tested 3 models: Picooc S3 Lite, Xiaomi Smart Scale 2 and Xiaomi Body Composition Scale 2 on a group of 10 people (weights from 52 to 105 kg) using Tanita BC-545N medical scales as a reference.
- 📊 Weight: All models showed error ±0.1-0.3 Kg - within the declared characteristics, but Picooc was more stable in fixing the values in repeated weighings (scattering). 0.1 quid 0.2 kilogram).
- 💪 Muscle mass: Picooc won by a margin - the error was 1.2 kg (vs. 2.1 kg in Xiaomi.
- 🍗 Fat percentage: The most problematic parameter. - Xiaomi Body Composition Scale 2 overstatement 3-5% um > 25. Picooc is more accurate, but also sins when measuring athletes (underestimation of the number of athletes). 2-3%).
It is important to understand that bioimpedance analysis (the method used in these scales) depends on the hydration of the body. If you drank a liter of water before weighing, your fat can drop by 1-2% regardless of the model.
Use scales in the morning on an empty stomach | Weigh without shoes and socks | Do not drink water 30 minutes before measurement |Repeat measuring 2-3 times and take the average |Comparing dynamics, not absolute figures-->
For athletes and people with a non-standard build (such as bodybuilders), it is better to consider scales with 8 electrodes (such as Tanita or Withings), but they are 2-3 times more expensive. If the budget is limited, the Picooc S3 Lite will be the optimal compromise.
Design and usability: what is more important – appearance or functionality?
From a design perspective, both brands follow a minimalist style, but there are nuances:
| Parameter | Picooc S3 Lite | Xiaomi Smart Scale 2 | Xiaomi Body Composition Scale 2 |
|---|---|---|---|
| Platform material | Tempered glass (6 mm) | Tempered glass (5 mm) | Tempered glass (6 mm) with anti-slip coating |
| Max, load. | 180 kg | 150 kg | 150 kg |
| Illumination of the display | White, automatic. | White, activated when pressed | RGB (16 colors), customizable |
| Dimensions | 300×300×25 mm | 300×300×23 mm | 300×300×25 mm |
Xiaomi Body Composition Scale 2 stands out RGB-It's a lighting system that can be customized to the interior or used as a progress indicator (e.g., green for weight loss), but the touch buttons on this model are less responsive than the physical button on Picooc. S3 Lite.The latter also wins in maximum load - 180 kg vs 150 kg, which is important for people with more weight.
Another thing is stability on rough surfaces: Picooc has rubber-laminated legs, whereas Xiaomi has plastic ones. If the bathroom floor is uneven, Xiaomi's scales can show Lo error (unstable position).
💡
To test the levelness of the surface, put the scales on the floor and press each corner one by one, and if the screen is flashing, the surface is uneven, you need a substrate.
3.Sync with apps: Mi Fit vs Picooc App
Here's where the key differences begin: Both brands work with proprietary applications, but the functionality and integrations are different:
- 📱 Picooc App: Sync with Apple Health, Google Fit, Samsung Health Data Export to Apple Health CSV (Display trends for 3 years (Xiaomi - only 1 year) minus: the interface is overloaded with advertising accessories
- 📱 Mi Fit (for Xiaomi): Integration with Zepp (for owners of smart watches Amazfit) Automatic calorie calculation (if you connect Mi Band) Cons: no data export, graphs are less detailed
The critical moment for iPhone owners is that the Xiaomi Smart Scale 2 doesn't sync directly with Apple Health. You'll have to use workarounds (like the Health Sync app), which is inconvenient. Picooc doesn't have that drawback.
Also, pay attention to synchronization speed. Xiaomi has Bluetooth 5.0 data almost instantly, while Picooc sometimes thinks about 5-10 seconds. If you care about speed, take Xiaomi. If you want analytics and integration, Picooc.
4. Additional functions: what is really useful?
Manufacturers like to add chips, but not all of them are equally useful.
- 👶 Family mode: Picooc: up to 16 profiles, automatic weight recognition (works stably) Xiaomi: up to 10 profiles, but often confuses users with close weight
- 👟 Sports metrics: Picooc S3 Lite shows viscosity index (an indicator of vascular aging) - a unique feature Xiaomi Body Composition Scale 2 assesses bone mass and water level in the body
- 🔋 Autonomy: Picooc: 4 battery AAA, enough 12-18 Xiaomi months: lithium battery, charging enough for 6-8 months (more convenient but requires recharging)
Note the viscosity index in Picooc, which correlates with cardiovascular risk and is rare in budget scales. However, to correctly display it, you need to enter pressure manually (the scales do not measure it!). Xiaomi has no analogue to this feature, but there is a metabolic age estimate - useful for motivation.
What is metabolic age?
If you need a scale for family use, you might want to choose Picooc because of its robust profile recognition, and the Xiaomi Body Composition Scale 2 will be more useful for athletes because of its detailed body composition analysis.
5. Compatibility with other devices: fitness bracelets, smartphones, PCs
Smart scales are rarely used alone — they're usually part of the gadget ecosystem. Here's how things go with compatibility:
- 📲 Smartphones: Picooc: Android 5.0+/iOS 10.0+ Xiaomi: Android 6.0+/iOS 10.0+ (But on iOS functionality is reduced)
- ⌚ Fitness bracelets: Picooc: works with Amazfit, Huawei Band, Honor Band via Google Fit Xiaomi: only with Mi Band and Amazfit (via Mi Fit)
- 💻 Data export: Picooc: CSV, integration with Apple Health/Google Fit Xiaomi: manual table entry only (no automatic export)
For Apple Watch or Garmin owners, Picooc is the clear choice, as it syncs with Apple Health. If you already have the Mi Band, it makes sense to take Xiaomi for full integration into the ecosystem.
💡
If you use multiple fitness trackers (like the Apple Watch during the day and the Mi Band at night), Picooc will be more versatile with support for Google Fit and Apple Health.
Also worth mentioning is the developer API: Picooc has an open API that allows you to integrate weights into your own applications (relevant to trainers or clinics), and Xiaomi has a closed API for most users.

7. Frequent problems and how to avoid them
Even the best smart scales have failures, and here are the typical problems and solutions.
- 🔄 Libras not included: For Picooc: check the batteries (even if they are new - sometimes factory defects) For Xiaomi: press and hold the 10 seconds button to reset
- 📵 Not synced with phone: Turn off Bluetooth on phone, then turn on Re-Remove scales from device list in Bluetooth settings and add again For Xiaomi: Update Mi Fit to the latest version
- ⚖️ Put the scales on a flat, hard surface (not on a carpet!) Calibrate the scales: stand on them, then take off your legs and wait for zeroing if there is an error. >0.5 kg – contact the service (possibly damaged sensors)
If the scales show an abnormally high/low percentage (e.g. 5% in a woman or 40% in an athlete), it is likely that the problem is incorrectly entered data (height, age, gender) or dehydration. Drink 1.5-2 liters of water per day for accurate measurements.
⚠️ Note: If you use scales to monitor medical signs (such as swelling during pregnancy), do not rely only on smart scales. For accurate diagnosis, you need professional devices (for example, Tanita with 8 electrodes).
