Siguro smart scale is on sale again for under five hundred. It has many features and users praise it

Smart diagnostic scales with phone connectivity usually start at higher prices – and those with a Czech app even higher. But right now, you can get the Siguro Smart Vital Coach S240B for 449 CZK instead of 599 CZK – this is the same price the scale was sold for during the January sales. It measures 14 body characteristics and has great reviews.

Quick summary:
✅ Makes sense if you want to track more than just weight and appreciate a Czech app with clear graphs.
⚠️ Consider if you require professional accuracy or direct integration with Samsung Health or Apple Health.
💡 For 449 CZK, you get a diagnostic scale with 14 functions, memory for 12 users, and a 3-year warranty – which is above standard in this price category.

Why this scale is interesting

Siguro Smart Vital Coach is among the affordable diagnostic scales that offer significantly more than just weight measurement. After connecting with the mobile app TUYA via Bluetooth, you get an overview of 14 body characteristics – from fat and muscle mass percentage to body water content, metabolic age, or visceral fat.

The TUYA app is completely in Czech, which is not a given for cheaper smart scales. Data is displayed in clear graphs, so you can track your progress over time. The scale remembers profiles for up to 12 users and can automatically recognize them based on measured values.

Key parameters in practice

The scale’s capacity is 180 kg. Measurement accuracy varies by load: 10 g for weights up to 10 kg, 50 g in the range of 10–100 kg, and 100 g above 100 kg. The display shows weight, while other values (fat, muscles, water, BMI, metabolic age, and more) can be found in the app.

The weighing surface is made of 6 mm thick tempered glass with dimensions of 28 × 28 cm. The display is backlit with a digit height of 27.5 mm – readability is good even in a dark bathroom. The scale automatically turns on when stepped on and turns off after measurement, which saves batteries. Power is provided by 4× AAA batteries, which are included in the package.

Connection to the phone works via Bluetooth 4.0. If the phone is not nearby, the scale will store the data, and the app will ask you if you want to import it retrospectively during the next connection.

What users say

On Alza, the scale has a rating of 4.6 out of 5 (62 ratings) and 90% of customers recommend it. Over 500 units have already been sold. Users most often praise the elegant design, simple installation, and clear Czech application. They also appreciate that each family member can have their own profile with measurement history.

Critical voices mainly concern measurement accuracy – some users report discrepancies during repeated weighing. However, it should be added that this is a common phenomenon for diagnostic scales in this price category, and the scale primarily serves to track trends, not for absolutely precise values. Several reviews mention privacy concerns due to the Chinese TUYA app – if this bothers you, consider entering less sensitive data or another scale with a European app (at a higher price).

Another practical note from reviews: the scale does not have direct integration with Samsung Health or Apple Health. Data can be transferred via Health Connect, but it requires additional setup.

When it doesn’t make sense

If you need professional accuracy at the InBody level or similar clinical devices, this scale won’t provide it – but no home scale in the price category up to several thousand CZK will. Similarly, if you require direct synchronization with Apple Health or Samsung Health without intermediate steps, you will have to opt for more expensive models from brands like Withings or Garmin.

For users who do not want to install any app and want to see all values directly on the scale’s display, this model is not suitable – only weight is shown on the display, other metrics are only available on the phone.

Verdict: who it’s worth it for

The Siguro Smart Vital Coach is a scale for those who want to track more than just kilograms and don’t need professional accuracy. For 449 CZK, you get diagnostics of 14 body characteristics, a Czech app with clear graphs, memory for the whole family, and an above-standard 3-year warranty. Conversely, if you require direct integration with Apple or Samsung fitness ecosystems, or if you mind the Chinese app, it’s worth looking for more expensive alternatives.

Do you only track kilograms on your smart scale, or are you interested in other body values as well?
