| Main trade-off | It reads through the feet only, Renpho gives no body-fat accuracy figure, and only weight shows on the scale. | It costs $599.95, its DEXA figure comes from a study of the earlier Body Scan, and the newest scores and Apple Health sync for new accounts need Withings+. |
|---|
| Key specifications | - Body composition method: Bioelectrical impedance through 4 electrodes in the platform. Renpho says current runs up through one foot, into the lower body and down the other foot, and the upper body is estimated with algorithms. The app shows 13 metrics: weight, BMI, body fat %, body water %, skeletal muscle, fat-free body weight, muscle mass, bone mass, protein, basal metabolic rate, subcutaneous fat, visceral fat and metabolic age. Renpho doesn't state the frequency
- Weighing: 6.6 to 400 lb (3 to 180 kg) in 0.1 lb (0.05 kg) steps. Units: lb and kg. Renpho's manual page lists the ES-CS20M among its models. It gives weight accuracy of ±0.3 kg at 50 kg, ±0.4 kg at 100 kg and ±0.5 kg at 150 kg
- Display: LED display. Renpho lists weight as the one body metric shown on the scale; the other 12 are in the app
- Users and ages: Unlimited profiles in the app, with automatic user recognition. The manual page says children under 10 and adults over 70 get weighing only, while Renpho's collection FAQ says children under 8
- Connectivity and app: Bluetooth, version 5 per the manual page. Works only with the Renpho Health app, which the App Store lists as requiring iOS 15.1 or later. The App Store also lists Apple Watch. Syncs with Apple Health, Fitbit, Samsung Health and MyFitnessPal
- Battery: Three AAA batteries, included. Renpho gives a battery life of up to 4.5 months
- Use guidance: Bare feet on the electrodes, a hard flat surface, and weighing at the same time each day. The scale switches off after 10 seconds. Renpho says to recalibrate it if it has been moved or turned upside down
- In the box: Elis 1 Smart Body Scale, three AAA batteries and a manual
| - Body composition method: Multi-frequency bioimpedance spectroscopy at 13 frequencies up to 800 kHz, against 3 frequencies up to 250 kHz on the earlier Body Scan, per Withings. It uses 12 electrodes, 8 in the platform and 4 in the handle, so the current runs from hands to feet. It reports fat and muscle for six body zones (arms, legs, torso and abdomen). Whole-body readings are body fat %, body water %, muscle mass, bone mass, visceral fat index and basal metabolic rate
- Weighing: Four weight sensors. Range 9 to 440 lb (5 to 200 kg) in 0.1 lb (50 g) steps. Units: kg, lb and st lb
- ECG, SpO2 and cardiovascular features: 6-lead ECG recorded over 30 seconds while you stand on the scale and hold the handle. SpO2 from a light sensor under your left thumb, which Withings calls a wellness feature. Also standing heart rate, pulse wave velocity, vascular age and a Nerve Response Score from the foot electrodes. In the US, Blood Pressure Insights notifications are a wellness score that Withings says doesn't measure your blood pressure
- Scan modes: A Daily Scan takes about 30 seconds and covers weight, segmental body composition, heart rate and pulse wave velocity by default. A Longevity Scan takes about 2 minutes, is offered every 7 days and adds ECG, SpO2, vascular age and the Nerve Response Score. Body composition, SpO2, ECG and Heart and Vascular Age need the handle. Without it you still get weight, BMI, pulse wave velocity and the Nerve Response Score
- Users and modes: Recognizes up to 8 users. The product page lists Athlete and Baby modes and says Pregnancy and Eyes Closed modes are coming, while a support article lists Weight-Only, Athlete and Pregnancy modes. Body composition is only available to people 16 or older
- Connectivity and app: Wi-Fi 802.11 b/g/n. The product page lists Bluetooth as coming soon, but Withings' installation guide pairs the scale over Bluetooth and offers a Bluetooth-only option. Needs the Withings app on iOS 18 or later, or Android 12 or later. Stores up to 16 readings when it can't sync
- Display: A 640 x 172 pixel color LCD in the handle, with two thumb buttons. Withings gives its size as 3.2, 3.4 and 3.5 in on different pages
- Battery and charging: Built-in rechargeable 3.7 V, 2,500 mAh lithium-ion battery that Withings says lasts up to 1 year per charge. A full charge takes up to 5 hours over the USB cable provided, and you can't use the scale while it charges
- Features that need Withings+: Heart Age and Glucose Resilience need a Withings+ subscription. Withings' FAQ of Jul 12, 2026 marks Glucose Resilience as coming soon, and the product page says feature availability depends on software updates. The product page's Withings+ box lists ECG cardiologist reviews, with 4 included. Baseline data and trends stay free

| Exact variant | Elis 1 (ES-CS20M by Renpho's part number), three AAA batteries included | BodyScan 2 with retractable handle and handle display, black, Wi-Fi, rechargeable |
|---|
| Dimensions | The scale's size and weight are unknown. Renpho's product page lists only a 400 lb capacity. | 12.8 x 14.1 x 0.7 in (325 x 357 x 18.5 mm), per Withings' product page. The page's comparison chart gives a total weight of 7.5 lb for the BodyScan 2. The weighing capacity is 440 lb (200 kg). |
|---|
| Installation | No installation. The three AAA batteries are included. Put the scale on a hard, flat floor, since Renpho says carpet causes inaccurate readings. Download the free Renpho Health app, create an account or use guest mode, and pair the scale over Bluetooth while standing on it with bare feet. | No installation. You set it up in the Withings app, with Bluetooth on, location permission and your Wi-Fi password. The app pairs the scale with a 6-digit code and then connects it to Wi-Fi. Withings recommends Wi-Fi, and says a scale set up without it loses most of its functions. It can't be set up from a computer. In the US, the ECG function needs its own activation. You give your state and a US phone number, and a board-certified cardiologist reviews your first ECG at no added cost. Withings says that US activation is for scales bought from a US retailer or online store. |
|---|
| Materials | Glass, per Renpho's product page. Renpho's manual page, which covers several scale models, lists tempered glass with HIPS plastic. | A reinforced aluminum chassis with a large glass platform, per Withings' product page, which calls the platform both high-strength tempered glass and ITO glass. It lists 12 integrated electrodes: 8 ITO electrodes and 4 stainless steel electrodes. The handle's materials are not stated by the manufacturer. The box holds the BodyScan 2, a USB-C cable and a quick installation guide. |
|---|
| Warranty | 18 months from the original retail purchase for buyers in the US and Canada, per Renpho's warranty terms. They apply to scales bought on Renpho's own site, and other sales channels may differ. The product page also says 18 months, but Renpho's manual page still says one year. Renpho repairs, replaces or refunds at its choice. Batteries made to diminish over time, cosmetic damage, accidents, liquid contact and unauthorized service aren't covered. | 2-year quality guarantee, per Withings' product page. The US store's terms of sale describe legal warranties under French law. They give no US warranty terms, so conditions, exclusions and claim steps weren't confirmed. |
|---|
| Returns | 30 days from delivery, per Renpho's shipping and returns page. If you return the scale for a personal reason, it must be unused and in its original packaging. You pay return shipping, and Renpho charges no restocking fee. If it arrives damaged or defective within 30 days, Renpho pays return shipping and gives a full refund or a free replacement. Contact support first, and Renpho then sends a prepaid label. | 30 days from receipt, per Withings' refund policy. One clause counts the 30 days from receipt and another from the purchase date. You start the return from your Withings account, print the label and send back the product with all its original items. The product page says free shipping and returns, but the policy says you pay return shipping after a withdrawal, so check the label cost first. Refunds go to the original payment method. Withings+ payments already made are non-refundable, with an exception if you weren't told about automatic renewal. |
