Quick Verdict
Pros
- 13 body composition metrics including BMI, body fat, water, muscle, bone, and visceral fat
- USB-C rechargeable battery — no fumbling with AAA batteries ever
- App syncs with Apple Health, MyFitnessPal, and Samsung Health

Quick Verdict
The RENPHO smart scale is a practical, well-priced body composition tracker that goes well beyond a plain number on glass. Three weeks in, I'm tracking weekly trends in body fat, water, and muscle mass — data that a regular bathroom scale simply can't give you. The USB-C charging is a genuine quality-of-life win, and the app's Apple Health sync means the numbers flow where you already look. It's not a medical device, and the body fat readings fluctuate between measurements, but as a motivation and tracking tool for the average person, the RENPHO Elis 1 earns a solid score. Rated 4.4 out of 5.
What Is the RENPHO Smart Scale?
The RENPHO Elis 1 is a Bluetooth-enabled bathroom scale that measures 13 body composition metrics using Bioelectric Impedance Analysis (BIA). Unlike a standard scale that only tells you your weight, it passes a tiny electrical current through your feet to estimate body fat percentage, water content, muscle mass, bone mass, visceral fat, and more. The 11-inch platform sits on 6mm tempered glass with four electrode contact points. It connects to the free RENPHO Health app over Bluetooth, and can sync with Apple Health, MyFitnessPal, and Samsung Health. It charges via USB-C — a refreshing change from scales that chew through AAA batteries every few months.

Hands-On Review
It arrived in a compact box on a Tuesday afternoon. Setup took about six minutes: download the app, create a profile, step on the scale. The Bluetooth pairing was instant — no code to punch in, no QR scan. The RENPHO Health app asked for my height, age, and gender, then it was ready. Stepping on felt solid. The 6mm tempered glass has a reassuring weight to it, and the platform didn't shift on my tile bathroom floor even when I stepped on the edge.
What surprised me was how differently my body composition read across the day. First thing in the morning, post-workout, after dinner — body fat percentage swung by as much as 2.5% between readings. That isn't the scale lying; BIA is sensitive to hydration and when you last ate. What matters is consistency: weigh yourself at the same time of day under the same conditions, and the RENPHO smart scale gives you reliable trend data. I started weighing myself every morning before coffee, and within two weeks the graph told a clearer story than a single number ever could.
The app is where the RENPHO scale either wins you over or frustrates you. It's functional but busy. The home screen shows your current reading, a trend graph for the past 30 days, and a row of metric tiles. Digging deeper, you can set weight goals, adjust units, and toggle data syncs. Linking to Apple Health worked seamlessly — my RENPHO body composition data now flows into the same dashboard as my walks and workouts. The baby mode is tucked in the settings menu and it's genuinely clever: weigh yourself, then hold your baby and the app subtracts your weight to show the infant's. My sister with a six-month-old called it the feature she didn't know she needed.
Two things nagged me. The body fat and water readings sometimes jumped between consecutive measurements — stepping off and back on gave numbers that differed by more than I'd expect from rounding. The electrode-only design (no hand sensors) also limits how deep the BIA signal travels. Professional medical-grade BIA uses hand-and-foot contact for a full-body reading. For the RENPHO's price point, this is expected — but worth knowing. Will I keep using it? Absolutely — the trend data is motivating in a way that a single number on a dial never was.
Who Should Buy It?
- Fitness-minded beginners who want more than weight — tracking body fat % and muscle mass alongside the number on the scale gives context that raw weight can't.
- Families with shared health goals where multiple people need to track progress separately. Unlimited profiles and auto-detection make it practical for households of any size.
- Parents of infants who want to monitor baby's growth at home without a separate baby scale — baby mode on the RENPHO Health app handles this without extra hardware.
- Users already in the MyFitnessPal or Apple Health ecosystem who want their body composition data flowing into the same place they log food and workouts.
Skip this if you only want to know your weight and don't care about apps. A basic $20 scale does that job. Also skip it if you need clinical-grade body composition accuracy — a DEXA scan at a medical facility is the only way to get that level of precision.
Alternatives Worth Considering
- Withings Body+ — slightly higher price but integrates more smoothly with a broader health ecosystem and includes a positioning guide for more consistent readings. Better option if you want a more polished app experience.
- Eufy Smart Scale P1 — comparable 13-metric BIA tracking at a similar price point, also USB-C. Eufy's app is simpler but has fewer integration options than RENPHO Health.
- Greater Goods Smart Scale — a simpler, no-frills alternative if you want app sync and body composition basics without the busier feature set of the RENPHO.
FAQ
It's accurate enough to track trends over weeks and months, not precise enough for clinical diagnosis. BIA (Bioelectric Impedance Analysis) scales are sensitive to hydration, time of day, and food intake, so consecutive readings can vary by 1–3%. Use it to monitor direction, not absolute values.
Final Verdict
After three weeks with the RENPHO smart scale, I'm comfortable saying it's the best budget-friendly body composition tracker you can grab on Amazon right now. The 13-metric BIA suite, USB-C charging, and broad app integration punch well above its price tag. Yes, the body fat readings fluctuate between measurements and the app could use a cleaner interface — but for tracking your health trends over weeks and months, those are manageable trade-offs. The baby mode is a genuine bonus for families, and unlimited user profiles make it practical for any household size. If you want a smart scale that does more than weigh you and won't require a second mortgage to afford, the RENPHO Elis 1 is a solid choice.
