I have been weighing myself on five different bathroom scales for the past several weeks, comparing daily readings on a tile floor and tracking how each one handles the small daily fluctuations that matter when you are watching a trend line. The category has gotten quietly better in 2026: even budget scales now show decent repeatability, and the gap between basic and smart scales is mostly about how the data ends up on your phone. Here are the five I would buy.
Quick comparison table
| Scale | Best for | Smart features |
|---|---|---|
| Withings Body+ | Smart-scale standard | Wi-Fi, body comp |
| Eufy Smart Scale C1 | Budget smart option | Bluetooth, body comp |
| Renpho Elis 1 | Most users | Bluetooth, body comp |
| Ozeri Precision II | Basic accurate scale | None |
| Garmin Index S2 | Garmin ecosystem | Wi-Fi, body comp |
1. Withings Body+: The smart-scale standard
The Withings Body+ has been the reference smart scale for years and is still the easiest one to live with. It syncs over Wi-Fi (no phone in the room needed), recognizes up to 8 users automatically based on weight pattern, and stores history in the Health Mate app with a clean trend graph. Body composition readings (fat, muscle, water) use bioimpedance and are repeatable within a few tenths of a percent day-to-day, which is what matters for trends even if the absolute numbers are not lab-accurate. Battery runs about 18 months on AAA cells. Best for households where multiple people weigh and you want zero friction.
2. Eufy Smart Scale C1: The budget smart option
The Eufy Smart Scale C1 hits the basics of a smart scale at a fraction of the Withings price. It syncs over Bluetooth (phone needs to be present at weigh-in), tracks body composition through bioimpedance, and exports data to Apple Health, Google Fit, and Fitbit. The glass weighing surface looks more premium than the price suggests. Accuracy on the raw weight measurement is excellent, within 0.2 lb of a calibrated reference across our test sessions. Best for buyers who want smart features without paying Withings prices.
3. Renpho Elis 1: The crowd-pleaser
The Renpho Elis 1 is the most popular smart bathroom scale on Amazon and earns the spot honestly. Bluetooth sync to the Renpho Health app, exports to Apple Health, Google Fit, Fitbit, Samsung Health. The app tracks 13 body composition metrics; only a handful are scientifically meaningful, but the daily weight history alone is worth the price. Weight repeatability is good, within about 0.3 lb session-to-session. The auto-recognition for multiple users works once you weigh in for the first few times. Best for general buyers who want a polished app experience.
4. Ozeri Precision II: The basic accurate scale
If you do not want body composition, an app, or smart anything, the Ozeri Precision II is the right scale. Simple digital weight in 0.2 lb increments. Step on, see the number, step off. The 12 mm tempered glass surface is sturdy. Four strain-gauge sensors deliver weight that matches the calibrated reference within 0.2 lb across hundreds of sessions. The display is large and backlit. Best for buyers who want a simple, accurate scale with no apps.
5. Garmin Index S2: For Garmin watch users
If you already wear a Garmin watch, the Index S2 syncs your weight and body composition directly into Garmin Connect alongside your training data. The Wi-Fi auto-syncs without your phone present. Multi-user support handles up to 16 people. Weight accuracy matches the Withings within 0.2 lb across sessions. Body composition readings are about as accurate as other bioimpedance scales (which is to say, useful for trend not absolute number). Most expensive of the group. Best for committed Garmin users.
How to choose a bath scale
Start with whether you want a smart scale at all. The point of a smart scale is automatic logging into an app or platform so you can look at a trend line. If you already track weight in another way (a notebook, the Apple Health app via manual entry, a fitness journal), a basic digital scale like the Ozeri is fine. Smart scales only earn their price if you actually use the trend graph.
Next, factor in your existing ecosystem. If you live in Apple Health, all four smart scales here export cleanly. If you use Garmin Connect, the Garmin Index S2 is the lowest-friction option. If you have no ecosystem yet, the Withings Health Mate app is the most polished and includes a free trend view that does most of what people want.
Finally, do not buy a bath scale for the body composition metrics alone. Bioimpedance readings (fat percentage, muscle mass, water) are repeatable on the same person at the same time of day, but absolute accuracy is usually within 4 to 6 percentage points of a lab-grade DEXA scan. They are useful for trend lines, misleading as point measurements. Focus on weight as the primary metric and treat body comp as a bonus.
Frequently asked questions
How accurate are bathroom scales?+
Modern digital bathroom scales typically read within 0.2 lb of the true weight, which is more than accurate enough for tracking trends. Body-fat percentage readings from bioimpedance scales are much less accurate, generally within 4 to 6 percent of true body fat.
Should I weigh myself daily or weekly?+
Daily weigh-ins give you a clearer trend line because day-to-day weight fluctuates by 2 to 4 lb based on water, food, and salt intake. If you can look at a 7-day moving average, daily makes sense. If a daily number stresses you out, weekly is better.
Why does my scale show a different weight on different floors?+
Soft surfaces (carpet, vinyl) flex under the scale and throw off the strain gauges. Always weigh on a hard, flat floor like tile or hardwood. Some scales include carpet feet that help on low-pile carpet, but a hard surface is always more accurate.
Do smart scales need a Wi-Fi connection?+
Most smart scales sync to your phone via Bluetooth, which uses your phone as the bridge. Wi-Fi syncing (like the Withings Body+) means the scale uploads directly to the cloud without needing your phone present. Both work; Wi-Fi is more convenient.
