The Eufy Smart Scale P2 Pro is the safest pick for most people: consistent readings, a genuinely useful app, and battery life that holds up for months. If you want a simpler, cheaper option with the essential metrics only, the Renpho Smart Scale covers that.
Check price on AmazonSmart scales split into two real tiers regardless of price: ones that just weigh you accurately and sync that number to an app, and ones that also attempt body composition metrics like body fat and muscle mass using bioelectrical impedance. The second category is worth knowing is inherently an estimate, useful for tracking trends over time rather than treating any single reading as exact.
We compared sensor count, app quality, and how consistently owners report the readings holding steady day to day, since a scale that swings wildly between similar readings is less useful than a simpler one that’s at least consistent.

The picks, compared
Eufy Smart Scale P2 Pro
A Bluetooth scale built around getting weight and body composition readings consistent day to day, syncing to a reasonably polished app that also connects to Apple Health and Google Fit.
What owners say: Consistency between readings is the specific praise, more than raw accuracy against a clinical measurement. Battery life lasting months on the included AAAs is the other recurring positive; the trade-off is no Wi-Fi, so your phone needs to be nearby to sync.
- Accurate and consistent measurements
- Long battery life
- Comprehensive app with trend tracking
- No Wi-Fi connectivity
- App can be slow to sync occasionally
Renpho Smart Scale
One of the most widely owned budget scales, tracking 13 metrics and automatically recognizing up to 10 household users without manual profile switching.
What owners say: The amount of data for the price is what owners point to most, particularly the automatic multi-user recognition for a shared household scale. Body fat readings shift with hydration level, worth weighing at a consistent time of day for trend tracking.
- Affordable with many metrics
- Multi-user support
- Syncs with fitness apps
- Body fat accuracy can be inconsistent
- No rechargeable battery
Greater Goods Digital Bathroom Scale with Body Fat
A simpler scale that works standalone without requiring the app, aimed at someone who wants a smart scale’s basic metrics without committing to constant app use.
What owners say: Not needing the app for daily use is the specific reason owners choose this one over more feature-heavy competitors. Fewer tracked metrics than the other picks here, a fair trade for the added simplicity.
- Simple and user-friendly
- Durable construction
- Works without app if needed
- Limited metrics compared to others
- App could be more polished
FITINDEX Bluetooth Body Fat Scale
The most metrics-dense scale in this list, tracking body age and subcutaneous fat alongside the standard weight and body fat numbers, with unlimited user profiles rather than a fixed household cap.
What owners say: The sheer depth of data is the consistent draw for owners who want to track more than just weight and body fat. The app interface feels more cluttered than the Eufy or Renpho apps, worth expecting a learning curve.
- Wide range of body composition metrics
- Unlimited user profiles
- Good value for features
- App design could be improved
- Readings can fluctuate with hydration
RENPHO Elis 1 Smart Scale
A smaller-footprint version of Renpho’s core feature set, built for people with limited bathroom space or who travel with their scale rather than leaving it in one spot.
What owners say: The compact size without giving up the core metrics is what owners point to specifically. The smaller platform feels less stable for larger feet, worth checking if that’s a concern before buying.
- Compact and lightweight
- Good feature set for size
- Multi-user support
- Smaller platform may be less stable for larger feet
- Battery life not as long as some
Etekcity Smart Scale for Body Weight
A build-quality-first pick with a reinforced glass platform, deliberately tracking fewer metrics (weight, body fat, BMI) in exchange for sensors that hold their accuracy over years of use.
What owners say: Staying accurate after years of daily use is the specific, repeated praise, distinct from most budget scales that owners report drifting over time. Fewer tracked metrics is the trade-off for that durability focus.
- Very sturdy and durable
- Accurate weight measurements
- App syncs with Apple Health and Google Fit
- Limited metrics beyond weight and body fat
- App can be slow to load data
Withings Body Smart Scale
The only Wi-Fi-connected scale in this roundup, syncing automatically without needing your phone nearby, paired with the most polished app experience and readings owners compare favorably to DEXA scans.
What owners say: Seamless syncing and readings that hold up against more clinical measurements are the standout praise here. It’s the priciest pick in this roundup and some advanced metrics sit behind a subscription, worth checking what’s included before buying.
- Wi-Fi + Bluetooth connectivity
- Exceptional build quality
- Detailed trends and insights
- Automatic user recognition
- Higher cost
- Some advanced metrics require subscription
How to choose
- Accuracy and Sensors. Look for scales with ITO-coated glass or multiple electrode sensors for better body composition accuracy. Owner reviews often indicate that scales with more sensors provide more consistent readings.
- App Integration and Features. The companion app should track trends over time and sync with popular health platforms like Apple Health or Google Fit. A clean, intuitive interface makes it easier to interpret your data.
- User Support. If multiple people will use the scale, choose one with automatic user recognition and unlimited profiles. Many budget scales support up to 8-16 users, which is sufficient for most households.
- Build Quality and Design. A sturdy platform with anti-slip pads ensures safety and longevity. Tempered glass is common, but thicker glass models tend to be more durable. Consider the size if you have limited floor space.
- Battery Life and Connectivity. Bluetooth-only scales often have longer battery life than Wi-Fi models, but Wi-Fi offers automatic syncing without your phone nearby. Check if the scale uses standard batteries or has a rechargeable option.
Frequently asked questions
How do budget smart scales measure body fat?
Budget smart scales use bioelectrical impedance analysis (BIA), sending a tiny electrical current through your body to estimate fat vs. lean mass. While not as accurate as DEXA scans, they provide a consistent trend when used under similar conditions (e.g., same time of day, hydrated).
Are expensive smart scales more accurate than budget ones?
Higher-end scales often use more electrodes or advanced algorithms, which can improve accuracy for body composition. However, for basic weight and BMI, many budget smart scales perform comparably. Owner reviews suggest that consistency matters more than absolute accuracy for tracking progress.
Can I use a smart scale without a smartphone?
Most smart scales require a smartphone for initial setup to view detailed metrics and trends. However, many will display weight on the scale itself even if your phone is not connected. Check the product specs for standalone functionality.
How many users can a budget smart scale support?
Most budget scales support between 8 and 16 individual user profiles. The scale can automatically recognize users based on weight range, but you may need to manually select your profile if weights are similar.
Do smart scales work with Apple Health or Google Fit?
Many affordable smart scales integrate with Apple Health, Google Fit, and Samsung Health. Check the app's compatibility list before purchasing. Renpho, Eufy, and Withings models are known for smooth integration.
How often should I replace the batteries in my smart scale?
Battery life varies by model and usage. Most scales last several months to over a year on a set of AAA batteries. Some scales, like the Eufy P2 Pro, can last up to 12 months with regular use. Rechargeable models are also available.
The verdict
The Eufy Smart Scale P2 Pro is the right default for most households, consistent readings and a genuinely useful app without the Wi-Fi subscription of the Withings pick. Go with the Withings Body Smart Scale if seamless syncing and premium build matter enough to justify the price, or the Renpho Smart Scale if you just want solid basics at the lowest cost.
