Choosing a smart body scale: Gofit S2, Gofit X6 Pro or inBody i8?
- Starting to track your weight on a moderate budget: Gofit S2 – 4 electrodes, 6 metrics on the display, 15 in the app.
- Want many metrics on the scale itself, no phone needed: Gofit X6 Pro – 4.8-inch colour display showing 8 metrics, 17 metrics in total.
- Training at the gym and need per-segment results: inBody i8 – 8 electrodes measuring arms, legs and trunk, 31 metrics.
How does a smart scale measure body composition?
All three Crénot scales use bioelectrical impedance analysis (BIA). When you stand barefoot on the scale, a very small current passes through your body between the electrodes. Fat conducts electricity less well than muscle and water, so from the measured resistance plus your height, age and sex, the scale estimates body fat, muscle mass, body water and other metrics.
The most important difference is the number of electrodes. A 4-electrode scale only sends current through the legs, so the upper body is estimated indirectly. An 8-electrode scale adds a handle and measures arms, legs and trunk.

Gofit S2: enough for the whole family
Gofit S2 shows 6 metrics on its display: weight, body fat, body water, muscle mass, bone mass and BMI. Connect it to the app over Bluetooth for visceral fat, subcutaneous fat, BMR, protein and body age – 15 metrics in all – saved as daily, monthly and yearly charts. It supports unlimited users, so it works well as a shared household scale.
Gofit X6 Pro: 8 metrics right on the scale
X6 Pro is the premium version of the S2. Its 4.8-inch colour display shows 8 metrics, adding heart rate and a body shape report, so you do not need to open your phone after each weigh-in. ITO-coated glass replaces steel electrodes for full contact under your feet. From the second reading, FeetID™ recognises each person and measures offline.
inBody i8: when you need per-segment numbers
inBody i8 has 4 electrodes on the platform and 4 on its retractable handle. The current passes through the whole body, so it analyses 31 metrics plus muscle and fat for each arm, each leg and the trunk. This is the kind of report you see at a gym, useful when building muscle and checking which side is weaker.
How to get consistent readings
- Place the scale on a hard, flat floor, not on a rug.
- After unboxing or moving the scale, skip the first 5 readings.
- Stand barefoot with dry feet; with inBody i8, hold the handle on its electrodes.
- Weigh in at the same time every day, for example in the morning before eating, so you can compare trends.
Pregnant women should not measure body composition, and people with implanted devices such as a pacemaker should not use bioelectrical impedance scales. Scale metrics are for tracking trends and do not replace a diagnosis from a doctor.
Frequently Asked Questions
Are smart scales accurate?
BIA scales give consistent results for tracking trends when you measure correctly and at the same time each day. An 8-electrode scale like inBody i8 measures the whole body, so it gives more detail than a 4-electrode scale.
Can the whole family share one scale?
Yes. All three support unlimited users; Gofit X6 Pro and inBody i8 also recognise each person automatically.
Where can I buy genuine Crénot scales?
Crénot products are sold officially at SIMI.vn, with an electronic warranty.
