Smart Scales Showdown: Withings vs. Renpho — Which Is the Best Choice?
1
Design, Build & Setup: First Impressions
Look & materials
We expect a bathroom scale to be discreet and sturdy. The RENPHO Elis 1 is slim, clear-tempered glass with a minimalist look that disappears into most modern bathrooms. It lists a 400 lb (180 kg) capacity — solid for most households.
The Withings Body Smart has a more premium feel: tempered glass top, thicker chassis, and a high-resolution color screen that reads like a small dashboard. It feels weightier and more “appliance” than the RENPHO.
Footprint, display readability & portability
Out-of-box setup & pairing
We tested both workflows and found them straightforward:
RENPHO setup: download Renpho Health, enable Bluetooth, create an account, step on the scale to wake and pair. Quick, app-first, and forgiving.
Withings setup: install Health Mate, create an account, pair via Bluetooth then configure Wi‑Fi in-app for automatic sync. Setup takes a minute longer but gives automatic cloud syncing thereafter.
Multi-user onboarding, build quality & slip resistance
Both scales use automatic user recognition and offer baby modes; RENPHO highlights “unlimited users,” Withings auto-detects multiple profiles and keeps them separated in the app. Build quality favors Withings (heavier, solid feel); RENPHO scores for portability and value. Both include rubber feet for slip resistance and a low profile that fits most bathroom styles — RENPHO for minimalist/compact spaces, Withings for a premium, tech-forward aesthetic.
2
Accuracy & Measurement Depth: What They Track
Weight accuracy & repeatability
We checked raw weight performance and found both scales give reliable step-on weight readings, but they take different approaches. Withings advertises precision to 50 g and consistently repeats results to a tighter band — you’ll notice the same decimal reading across repeated steps. RENPHO reports weight with 0.2 lb (0.05 kg) increments and is dependable for everyday tracking, though you may see ±0.2–0.4 lb jitter between consecutive readings.
Body composition metrics compared
We compare what each reports and how useful those numbers are.
RENPHO typically provides around 13 metrics, accessed in the app:
Withings reports 8 advanced metrics, with additional clinical features:
How BIA-based measurements behave
Both use bioelectrical impedance analysis (BIA): a tiny current runs through the body and the scale estimates tissue composition. BIA gives trends that are useful for tracking direction-of-change, not exact clinical values. Withings uses multi-frequency/precision tech (tighter repeatability), while RENPHO gives “physician-style” readouts in the app that are very useful for home monitoring but can diverge from medical-grade scanners.
Common sources of error & tips for consistency
We recommend using these scales to track trends (weekly/monthly) rather than obsessing over single measurement differences.

Apps, Connectivity & Smart Features: Which Ecosystem Wins?
App experience
We found the RENPHO app simple and functional — quick setup, clear daily/weekly/monthly trend lines, and straightforward goal entry. Withings’ Health Mate is more polished: richer visuals, motivational cards, and clearer clinical-style insights that make trends easier to act on.
Bluetooth vs Wi‑Fi syncing & auto‑upload
Withings wins on reliability thanks to Wi‑Fi plus Bluetooth: weigh-ins sync automatically even when our phone isn’t nearby. RENPHO uses Bluetooth only, so data upload requires the phone nearby and can occasionally miss a weigh-in if Bluetooth is off.
Third‑party integrations & multi‑user recognition
Data visualization, trend tracking & coaching
Withings provides deeper trend analysis, heart-rate at weigh-in insights, weekly progress emails, and light coaching nudges. RENPHO gives reliable trend charts and goal setting but lacks the same level of contextual coaching or health‑insight cards.
Firmware updates, privacy & data export
Withings pushes firmware over Wi‑Fi and has clearer, industry‑grade privacy controls plus straightforward data export (CSV/PDF). RENPHO updates occur via the app over Bluetooth; it offers third‑party sync and basic export options, but Withings is stronger if you need granular privacy controls or easy exports for clinicians.

Price, Value & Real-World Use Cases
Upfront cost vs long‑term value
We compare sticker price to what you actually use every day. RENPHO (~$20) gives core smart features at a very low entry cost — great for testing smart scales without commitment. Withings (~$100) asks more up front but delivers longer battery life (Withings advertises 15 months, batteries included), a high‑resolution screen, Wi‑Fi auto‑sync, and clinically minded measurements that pay off over months and years if you rely on consistent data and seamless cloud backup.
Day‑to‑day: battery, support & reliability
We found Withings more “set it and forget it”: automatic Wi‑Fi sync, firmware updates over the air, and clearer privacy/export options. RENPHO requires Bluetooth and a phone nearby for consistent syncing, but it still reliably tracks weight and body metrics for families on a budget. Expect RENPHO’s replaceable batteries to last months depending on use; Withings explicitly targets longer battery life.

Quick pros / cons
Final Verdict: Which Scale Should You Buy?
We’d pick RENPHO for most users seeking best value and comprehensive metrics on a budget; it’s feature‑rich and reliable.
However, Withings is our overall winner for accuracy, Apple/Smart Home integration and baby/athlete needs — choose Withings if ecosystem, Wi‑Fi syncing and medical‑grade data matter. Grab Withings for precision and ecosystem, RENPHO for budget value.

I personally went with Withings for the design and ecosystem fit. It just looks nicer in the bathroom and the app felt more polished.
Not a huge fan of the RENPHO app layout — feels more cluttered.
If money’s tight, RENPHO is still a great value though.
Design sells me too. My bathroom finally looks like an adult space after I swapped to Withings 😅
Design and app polish are common deciding factors — glad the article helped with that angle. Thanks for sharing your choice!
Ugh, my RENPHO keeps disconnecting sometimes. App says data not found and I have to re-pair. Maybe Bluetooth on my phone is flaky? lowkey annoyed. Anyone else have connectivity issues? ios 14 btw, not updated yet — might be the problem.
Also the little glass surface cracks easily if you drop stuff on it, so don’t do that like I did 😂
Sorry to hear that, Daniel. Bluetooth can be flaky on older OS versions. Try clearing the app cache, re-pairing, and making sure the RENPHO app has background permissions. If problems persist, firmware updates or contacting RENPHO support can help.
I had pairing issues too until I disabled Bluetooth for other devices and reconnected. Also made sure Bluetooth was set to ‘always allow’ for the app.
I fixed flaky sync by letting the app sync to Apple Health, then the phone shows the data there even if RENPHO app lags.
Great write-up! I bought the RENPHO last year and this comparison rings true.
What I like about RENPHO: it’s cheap, syncs fine with my phone, and the metrics are surprisingly consistent for daily tracking. What I don’t like: the app UI is meh and sometimes the body fat number jumps a little after a workout.
Also — for anyone tracking trends, consistency matters more than absolute accuracy. Use the same scale every time and you’ll spot real changes fast.
Do you use their app or sync it through Apple Health? I’m on iPhone and wondering if the integration is reliable.
Totally agree. I used RENPHO for months and the numbers were all over the place right after cardio. If you measure first thing in the morning it’s steadier.
Thanks for sharing your experience, Sarah — that’s exactly the point we tried to make in the piece about consistency vs absolute accuracy. Good tip about post-workout spikes!
Love that the Withings has a baby weight mode — I need that for my niece! 😍
Quick q: does the RENPHO allow manual weight entry into the app? Sometimes I weigh on a different scale at the gym and want to log it.
Withings’ baby mode definitely simplifies things. RENPHO apps often allow manual entries depending on the app (some versions support manual input or sync via Apple Health/Google Fit where you can add entries). Check your RENPHO app settings.
Most apps let you add manual entries. I add gym weigh-ins to Apple Health and they merge fine with RENPHO data.
Tech nerd take: Wi‑Fi (Withings) means your scale can upload data straight from the device to the cloud; Bluetooth (RENPHO) requires your phone nearby to sync. Wi‑Fi is more seamless but slightly more setup.
For households where multiple people weigh themselves, Wi‑Fi + auto-recognition is helpful.
Also security: Withings has a better privacy policy in my view — check endpoints and where your data lands.
Can confirm. Withings saved me from manually syncing for months — bliss.
Right — we mentioned the sync difference in the piece. If someone wants zero interaction, Withings’ Wi‑Fi and multi-user auto-recognition are strong selling points.
