Wyze

Smart scales have evolved far beyond simple weight measurements. In 2025, body composition tracking is a key feature for anyone serious about health and fitness—and Wyze offers two compelling options: the Wyze Scale X and the Wyze Scale Ultra. Both sync seamlessly with the Wyze app, but they cater to slightly different needs. This comprehensive comparison will help you decide which smart scale delivers the best body composition tracking for your lifestyle.

Design and Build Quality

The Wyze Scale Ultra features a sleek, modern design with a large tempered glass platform and a vivid color display that shows your weight, weather, and even a personalized greeting. Its footprint is slightly larger, making it more stable on carpet or uneven floors. The Wyze Scale X, on the other hand, opts for a minimalist matte finish with a smaller, monochrome LCD screen. While both are durable, the Ultra feels more premium—but the X is lighter and easier to move around.

Body Composition Metrics: What Do They Measure?

Both scales use bioelectrical impedance analysis (BIA) to estimate body composition. The Wyze Scale X tracks up to 12 metrics including weight, body fat percentage, BMI, lean mass, and bone mass. The Wyze Scale Ultra goes further, offering 13 metrics—adding visceral fat rating and a more detailed muscle mass breakdown. For most users, the X provides plenty of data, but if you're a fitness enthusiast or managing specific health conditions, the Ultra's extra insights can be invaluable.

Key Metrics Comparison

• Weight & BMI: Both scales are accurate to 0.1 lb (0.05 kg) and sync automatically.
• Body Fat %: Ultra uses dual-frequency BIA for slightly better accuracy in tracking changes over time.
• Muscle Mass: Ultra provides segmental muscle mass (arms, legs, trunk) while X gives total.
• Visceral Fat: Only available on the Ultra—critical for assessing metabolic health.
• Bone Mass & Water %: Both offer these, but Ultra's trends are more granular.

If you're serious about body composition tracking, the Wyze Scale Ultra is the clear winner. Its additional metrics and trend analysis help you see beyond weight, making it ideal for users who track macros, follow strength training programs, or monitor health conditions like osteoporosis or edema.

App Integration and Ease of Use

Both scales pair with the Wyze app via Bluetooth. The setup takes under two minutes: step on, and the scale auto-detects up to 8 users. The app dashboard displays trends, goal setting, and historical data. The Wyze Scale Ultra also integrates with Apple Health, Google Fit, and Fitbit—while the Scale X only supports Apple Health and Google Fit. For fitness enthusiasts using wearables, the Ultra’s broader compatibility is a plus.

Smart Home Integration

Both scales work with Wyze’s ecosystem. For instance, you can create routines that trigger a Wyze Chime Controller to play a motivational sound when you hit a weight goal, or log your weigh-in to a spreadsheet via IFTTT. The Ultra supports more advanced automations, like changing your Wyze Lock Bolt's settings based on morning weight trends (e.g., “weight under target → unlock door to gym”).

Battery Life and Power

The Wyze Scale X uses four AAA batteries, which last about 6–8 months with daily use. The Wyze Scale Ultra has a built-in rechargeable battery that lasts up to 12 months on a single charge. The Ultra also includes a USB-C charging cable—no need to replace batteries. For convenience, the Ultra wins, but the X’s replaceable batteries are easier to swap in a pinch.

Price and Value

In 2025, the Wyze Scale X retails for around $25–$30, while the Wyze Scale Ultra is priced at $45–$55. The $15–$25 premium for the Ultra buys you a color display, rechargeable battery, extra metrics, and broader app compatibility. If you’re budget-conscious and only need basic weight and body fat tracking, the X is a solid choice. But for comprehensive body composition analysis, the Ultra offers significantly better value per dollar.

Who Should Buy Which?

• Choose Wyze Scale X if: You want a reliable, affordable smart scale for weight and basic body fat tracking, and you don’t mind replacing batteries occasionally.
• Choose Wyze Scale Ultra if: You’re a fitness enthusiast, athlete, or health-conscious person who needs detailed metrics like visceral fat and muscle distribution, plus seamless integration with your smart home and wearables.

Final Verdict

Both scales are excellent within their price brackets. The Wyze Scale X is a fantastic entry-level smart scale that covers the essentials. But if you’re serious about body composition tracking in 2025, the Wyze Scale Ultra is the better investment. Its extra metrics, longer battery life, and richer display make it a true companion for your health journey—especially when paired with Wyze’s growing ecosystem of smart home devices.

Frequently Asked Questions
