Yunmai Premium Smart Scale has 50,000+ reviews on JD.com with a 4.4/5 rating at ¥249 ($35). Users appreciate the comprehensive 15-body metric tracking including body fat, muscle mass, bone mass, and visceral fat, the elegant tempered glass design with LED display, and the automatic Bluetooth sync with the Yunmai app. The main complaints are the foot sensors not detecting contact consistently (requiring adjustment), the app requiring Chinese phone number registration, and the readings varying slightly between consecutive measurements. Conclusion: ✅ Worth Buying — the most feature-rich smart scale under ¥300 for health tracking enthusiasts.

Introduction

Yunmai (云麦) is a leading Chinese smart scale brand with a strong reputation for accuracy and comprehensive body composition analysis. The Premium Smart Scale uses BIA (Bioelectrical Impedance Analysis) technology to measure 15 body metrics, going far beyond simple weight tracking.

At ¥249 ($35), the Yunmai Premium sits in the mid-range of smart scales, competing with the Renpho Scale and Huawei Scale 3. It offers more metrics than the Xiaomi Fat Scale while maintaining a reasonable price point.

Design and Build Quality

The Yunmai Premium features a 30cm × 30cm tempered glass platform with ITO (Indium Tin Oxide) conductive coating on the surface, eliminating the need for visible metal electrodes. The surface is clean, white, and easy to clean. The LED display is bright and shows weight within 1-2 seconds of stepping on.

The scale includes a built-in handle mechanism that unfolds from the side — you lift it while standing on the scale to measure upper body metrics. This handle houses additional electrodes for more accurate full-body BIA measurement.

At 2.5cm thick, it’s slim enough to slide under furniture. The four AAA batteries (included) last about 12 months with daily use. The scale auto-powers on when stepped on and auto-off after 10 seconds.

“I switched from a basic Xiaomi scale and the difference in data depth is huge. The Yunmai shows 15 metrics vs 8. The handle mechanism for upper body measurement gives a more complete picture. My favorite feature is the automatic Bluetooth sync — I open the app and data is there. No phone needed during weighing.” — JD.com verified buyer

Performance

The scale delivers consistent weight measurements within ±50g. Body fat percentage accuracy is within ±2% of DEXA scan results based on user comparisons, which is good for a home BIA device. The 15 metrics include weight, BMI, body fat %, water %, muscle mass, bone mass, visceral fat level, BMR, body age, protein, subcutaneous fat, body type, fitness score, and body composition.

The Athlete Mode adjusts the algorithm for physically active users whose denser muscle mass would otherwise skew body fat readings. This is a useful feature not found on cheaper scales.

The handle integration improves upper body measurement accuracy. Users report that readings with the handle are more consistent than foot-only measurements, particularly for visceral fat and muscle mass.

“I use this scale every morning after waking up. The consistency is good — if I weigh myself 3 times in a row, the weight varies by about 50g and body fat by 0.3%. The visceral fat reading has been eye-opening and motivated me to improve my diet. The app graphs are useful for tracking trends.” — JD.com verified buyer

User Reviews by Theme

Data Completeness

“The 15 metrics are genuinely useful. Beyond just weight and body fat, I track muscle mass and visceral fat closely. The body age metric was a wake-up call. The app shows trends over weeks and months which is motivating.” — JD.com verified buyer

💡 Summary: 15 metrics provide comprehensive body composition analysis. Useful for tracking fitness progress.

Consistency

“Readings are consistent day-to-day. Body fat percentage typically varies 0.2-0.5% between consecutive weigh-ins. The scale recognizes me automatically (supports multiple users). The handle measurement improves accuracy for upper body metrics.” — JD.com verified buyer

💡 Summary: Good measurement consistency. Handle integration improves upper body analysis accuracy.

App Experience

“The Yunmai app is well-designed with clear charts and trends. The Chinese phone number registration requirement is annoying for overseas users. Once registered, the app works well with iOS and Android.” — JD.com verified buyer

💡 Summary: App is polished and functional. Registration requirement can be a barrier for international users.

Foot Detection

“Sometimes the scale doesn’t detect my feet properly, especially if they’re dry. The display shows ERR until I adjust my foot position. This happens maybe 1 in 10 times. Damp feet improve detection.” — JD.com verified buyer

💡 Summary: Foot detection can be inconsistent with dry skin. Easy to resolve by repositioning or slightly dampening feet.

Purchase Recommendations

✅ Worth Buying (¥249)

Best for fitness enthusiasts who want detailed body composition tracking beyond weight. Ideal for anyone following a structured fitness or weight loss program who needs data-driven insights.

💰 Premium Pick

The Yunmai Premium’s handle-based measurement makes it superior to foot-only alternatives for upper body analysis. Worth the ¥70 premium over the Renpho ES-PCS19 if you want the most detailed data.

⚠️ Budget Warning

At ¥99, the Xiaomi Fat Scale 2 offers basic weight and body fat tracking. Fine for casual users who don’t need 15 metrics or upper body analysis. The Yunmai is worth the premium for serious fitness tracking.

FAQ

Q: Yunmai Premium vs Xiaomi Fat Scale 2 — which is better? A: The Yunmai Premium has more metrics (15 vs 8), includes Athlete Mode, has a handle for upper body measurement, and offers better accuracy. The Xiaomi is ¥150 cheaper and sufficient for basic weight and body fat tracking.

Q: How accurate is the body fat measurement? A: BIA-based body fat is within ±2% of DEXA scan results for most users. Hydration levels, food intake, and time of day affect readings. For best consistency, measure at the same time daily (morning before eating/drinking).

Q: Can multiple family members use the same scale? A: Yes, unlimited user profiles. The scale automatically recognizes users based on weight and stores data to the correct profile. The app manages individual user histories.

Q: Does the scale work without the app? A: Yes, it displays weight and estimated body fat on the LED display. All 15 metrics require the app for viewing. The Bluetooth sync stores data for later viewing.

Q: Is the Yunmai Premium suitable for very light or very heavy individuals? A: The minimum detection weight is 5kg (suitable for small children with assistance). The maximum is 180kg, accommodating a wide range of users.
