The short answer: The RENPHO Smart Scale (like the classic Body Fat Scale) is better for most people because it offers detailed body metrics, Wi-Fi/Bluetooth connectivity, and a proven app, while the Elis 1 is a budget-friendly option that focuses on essential weight tracking with a sleek design, but it lacks the advanced metrics and app integration that serious fitness trackers need.
RENPHO offers two popular lines: the Elis 1 and the Smart Scale series (which includes models like the RENPHO Smart Scale with Bluetooth and the newer Wi-Fi versions). The Elis 1 is a minimalist digital scale that measures weight only, with a tempered glass platform and a simple step-on activation. It is designed for users who want a no-fuss, accurate weight measurement without extra features.
In contrast, the Smart Scale series is part of RENPHO’s connected ecosystem. It measures not just weight but also body fat percentage, BMI, muscle mass, bone mass, and more, using bioelectrical impedance analysis (BIA). It syncs with the RENPHO app via Bluetooth or Wi-Fi, allowing you to track trends over time, set goals, and even share data with fitness apps like Apple Health, Google Fit, and Fitbit. The Smart Scale is geared toward fitness enthusiasts, dieters, and anyone who wants a comprehensive view of their body composition.
The most significant difference is the data you get. The Elis 1 gives you a single number: your weight. The Smart Scale provides up to 13 body metrics, including body fat percentage, BMI, muscle mass, bone mass, and water weight. If you are serious about tracking body composition changes, the Smart Scale is the clear winner.
Accuracy is another consideration. Both scales use precision sensors, but the Smart Scale’s BIA technology requires inputting your age, height, and gender to calculate body fat and other metrics. The accuracy of these readings can vary based on hydration levels and body composition, but they are consistent enough for trend tracking. The Elis 1, being a weight-only scale, is simpler and less prone to error in that regard. However, neither scale is a medical device, and they should not replace professional health assessments.
App integration is a major differentiator. The Smart Scale syncs with the RENPHO app, which offers detailed charts, trends, and even a baby mode for tracking infant weight. You can set goals and see your progress over weeks and months. The Elis 1 has no app connectivity at all, so you must log your weight manually if you want to track it. For those who value data analysis and convenience, the Smart Scale is essential.
Both scales feature a tempered glass platform and are available in multiple colors. The Elis 1 is slightly more compact and has a minimalist aesthetic, making it a good fit for small bathrooms. The Smart Scale is similar in design but often includes a larger LED display and a more robust base. The Elis 1 uses a step-on activation with a simple display that shows weight once you step on, while the Smart Scale requires a moment to measure body composition and then displays the weight and other metrics.
When it comes to weight capacity, both handle up to 400 pounds (about 180 kg), which is standard. The Smart Scale models typically have a slightly higher capacity on some versions, but not significantly.
In terms of durability, both are well-built, but the Smart Scale’s extra electronics for body composition may be slightly more prone to issues over time, though RENPHO is known for reliable products. The Elis 1 is simpler and likely more robust in the long run if you don’t need the extra features.
Price is where the Elis 1 shines. It is typically priced lower than the Smart Scale, making it an attractive option for budget-conscious buyers. However, the Smart Scale often goes on sale, and the difference in price might be as little as $10 to $20, depending on the model and promotions. Considering the additional features, the Smart Scale offers significantly more value for a modest price increase.
If you only need to track weight and don’t care about body composition, the Elis 1 is a solid, cost-effective choice. But if you are willing to spend a little more for a scale that can help you understand your body better and keep you motivated with app-based tracking, the Smart Scale is the better investment.

Users of the Elis 1 often praise its simplicity and accuracy for weight measurement. It is easy to use, has a clear display, and does not require a smartphone to function. However, some users note that the lack of connectivity means they often forget to log their weight, leading to inconsistent tracking.
The Smart Scale, on the other hand, offers a more engaging experience. The app is intuitive and provides a comprehensive view of your health trends. Users report that the body composition readings are consistent, though they may not match professional DEXA scans. The app also allows multiple users to sync their data automatically, which is great for families. The main drawback is that you need to have your phone nearby for Bluetooth models, though Wi-Fi versions sync automatically.
One common issue with both scales is that the BIA measurements (on the Smart Scale) can be affected by factors like wet feet or movement, leading to slightly inconsistent readings. For the most accurate results, use the scale on a hard, flat surface, and measure at the same time each day, ideally in the morning before eating or drinking.
Q: Can I use the RENPHO Smart Scale without the app?
A: Yes, you can use it as a regular scale to see your weight on the display. However, you will not see the body composition metrics unless you connect to the app, as those are only displayed in the app.
Q: How often should I replace the batteries?
A: Both scales use AAA batteries (included) and typically last 6 to 12 months with normal use. The Smart Scale may drain faster if you use the app frequently, but it is not a significant issue. Always replace them with new batteries of the same type.
Q: Which scale is better for multiple users?
A: The Smart Scale is much better for multiple users because it can recognize up to 8 different users and automatically assign the data to the correct profile in the app. The Elis 1 simply shows weight, so you would need to track manually.
