Body fat percentage from a bathroom scale is, depending on who you ask, either a useful directional trend line or a number invented by elves. Mostly it’s a little of both. The reality is that the cheap consumer scales we put in our bathrooms use bioimpedance — a tiny electrical current through your feet — and the results are very repeatable, even if they’re not perfectly accurate.

I tested three of the most-recommended smart scales of 2026 in my Los Angeles bathroom for six weeks: the Withings Body Smart, the Renpho Elis 1, and the Eufy Smart Scale P3. I weighed myself on all three every morning at the same time, in the same clothing (none), after the same trip to the bathroom (you know the one). Here’s what I learned.

The test setup

I lined the three scales up against the bathroom wall, switched between them each day, and logged everything in a Google Sheet because my actual interest is whether the apps would tell me consistent things over time. I also weighed myself once a week at my doctor’s office on a calibrated medical scale, just to have a ground-truth.

All three scales tracked my weight to within roughly half a pound of the doctor’s scale on any given day. That’s reassuring. Where they disagreed wildly was body fat percentage — a five-point spread on the same morning across the three. So treat that number as a trend, not a fact.

Withings Body Smart — $99

This is the scale I’d recommend to most people. Withings has been doing this for over a decade, and it shows in the boring places: the app pairs in 40 seconds, the daily weigh-in syncs to Apple Health automatically, the visual weight history is the cleanest of the three. The screen on the device itself shows you weight, then BMI, then the weather for the day, which is the kind of small, delightful detail that justifies a premium price.

Two minor gripes. First, the on-device display is small — my mom borrowed mine and complained. If you have less-than-perfect close vision, look elsewhere. Second, the Withings app pushes you toward a $9.99/month “Withings+” subscription that you absolutely do not need. The free features are the features that matter.

Renpho Elis 1 — $30

The Renpho Elis 1 is the best $30 scale on the market and I would happily give one to a friend who told me they were tired of guessing whether their jeans had gotten tighter. It tracks all the same body composition metrics, syncs to Apple Health and Google Fit, and the app — surprisingly — is fine. Not great, but fine.

The catch: there are now four scales called “Renpho Elis 1.” Different versions ship with slightly different sensors and the cheapest version skips the heart-rate feature. If you care about that, check the listing carefully before you buy. The differences between models are often a single line in the product description.

Eufy Smart Scale P3 — $59

The Eufy P3 has the prettiest hardware of the three — a glossy black slab with a hidden LED display that only lights up when you step on it. If you have a minimalist bathroom and you genuinely care that your scale doesn’t look like a 1990s bathroom appliance, this is the one.

The disappointment was the app. EufyLife is clearly maintained by a team that maintains five other apps. The weight log is fine, the body-composition breakdown is fine, but Apple Health sync repeatedly broke during my test — I had to re-link it twice. For a $59 scale, this is irritating but not disqualifying.

The one I sent back

I’d planned to also test a Garmin Index S2 in a fourth slot. It arrived, I set it up, and within 48 hours I’d boxed it back up. The Wi-Fi setup is a hostile UX, the on-device interactions are confusing, and at $150 it’s three times the price of the Renpho without doing anything three times better. If you live inside Garmin’s ecosystem (a Forerunner or a Fenix watch), the integration might be worth it. For everyone else, no.

What I actually do every morning

I weigh myself two or three mornings a week now, not every morning. The body fat number I treat as a directional trend over four weeks, not a number to react to day-to-day. I never weigh myself on the day after a long flight or a Korean BBQ dinner, because the bioimpedance reading is meaningfully off when you’re holding extra water.

This is, I realize, the boring, mature answer that I would not have wanted when I was twenty-two. Body data is useful when it informs decisions and tedious when it becomes the decision. The right scale is the one that gets you to that calm, slightly less-attached relationship to the number on the floor.

Bottom line

If you want a single answer: buy the Withings Body Smart. It’s been the most consistent and the least annoying of the three, and the Apple Health sync just works.

If you want a great scale for the cost of a Sweetgreen lunch order, the Renpho Elis 1 is the value pick — just double-check which version you’re buying.

If the aesthetic of your bathroom is non-negotiable, the Eufy P3 earns its premium for the design — just don’t expect the app to surprise you.
