SmartScan Ultra vs. SmartScan Pro: Which Should You Choose?
The RunStar SmartScan Ultra and SmartScan Pro both combine eight electrodes with dual-frequency BIA for body composition tracking.
So, how do you choose between them?
The most useful differences are in the everyday experience: the platform’s electrode design, the information shown on the display, and how the scale is powered.
Here’s a practical comparison.
SmartScan Ultra vs. SmartScan Pro at a Glance
| Feature | SmartScan Ultra | SmartScan Pro |
|---|---|---|
| Electrode system | Eight electrodes with ITO-coated foot sensing areas | Eight electrodes with metal foot contact pads |
| Measurement technology | Dual-frequency AC BIA | Dual-frequency AC BIA |
| Regional analysis | Arms, legs, and trunk | Arms, legs, and trunk |
| Display | VA, 8-in-1 | TFT LCD, 7-in-1 |
| Displayed information | Weight, weight changes, body fat, BMI, muscle mass, visceral fat, body type, weight trends | Weight, BMI, Visceral Fat, Body Fat, Muscle Mass, Bone Mass, Body Water |
| Power | Four AAA batteries | Rechargeable battery with USB Type-C charging |
| App | Starfit | Starfit |
What Do Both Models Offer?
Both models use hand and foot electrodes and support segmental body composition analysis. This adds regional estimates to overall measurements, giving you more detail to review over time.
Both also use dual-frequency BIA. These shared specifications make either model worth considering if you want to move beyond a basic foot-contact scale.
If these technologies are new to you, our guides to 8-electrode vs. 4-electrode smart scales and dual-frequency BIA explain the basics.
Difference 1: Foot Electrode Design
The Ultra uses ITO-coated foot electrodes with a larger sensing area. The Pro uses distinct metal contact pads.
With either model, correct barefoot contact matters. Follow the foot placement instructions and maintain contact throughout the measurement.
When comparing the designs, think about which platform you would find easier to use regularly. A larger sensing area is a design feature; it does not, by itself, establish a particular accuracy advantage.
Difference 2: What You See on the Display
The Ultra’s display emphasizes weight changes and trends alongside selected body composition results. The Pro’s seven displayed measurements are weight, BMI, visceral fat, body fat, muscle mass, bone mass, and body water.
Choose based on the information you want to check immediately after stepping on the scale.
An eight-item display does not automatically mean a more comprehensive app report than a seven-item display. The on-device selection and the app’s reporting features serve different purposes.
Difference 3: Batteries or Recharging
The Ultra uses replaceable AAA batteries. The Pro supports USB Type-C charging.
This is a simple preference, but one that affects ownership. Consider whether replacing batteries or periodically charging a device fits your household routine better.
Which Model Fits Your Routine?
Choose SmartScan Ultra if you prefer its larger ITO-coated sensing areas and want weight changes, visceral fat, and weight trends included in the on-device display.
Choose SmartScan Pro if you prefer a rechargeable model and want its selection of seven displayed measurements, including visceral fat, bone mass, and body water.
For either model, use consistent measurement conditions and review longer-term patterns. Body composition readings are estimates for home wellness tracking.
Compare the current offers for SmartScan Ultra and SmartScan Pro, then choose the combination of display, design, and power source that suits you.
