Quick Verdict
The Renpho smart scale is the best value body composition scale under $30. Weight accuracy is excellent (±0.2 lbs). Body fat and muscle readings are BIA estimates — useful for tracking trends, not clinical precision. The free app is genuinely good and syncs with every major fitness platform. For the price, nothing comes close.

Most people know weight and BMI, but the Renpho scale measures 11 additional metrics via bioelectrical impedance analysis (BIA). Here's what each one tells you:
Michael R. — Verified Amazon Purchase
"I was skeptical about a $25 scale doing all this, but the weight readings are dead-on accurate — I confirmed against a calibrated gym scale. The body fat % changes make sense with my diet and exercise changes. The app is clean and easy to use. Honestly surprised at the quality."
Jennifer K. — Verified Amazon Purchase
"I've been using this for 18 months. I like that my whole family can use it — we each have our own profile and it automatically recognizes us. My doctor was surprised by how consistent my body fat readings are with her office scale. For $25, this is unreal."
David T. — Verified Amazon Purchase
"Great scale overall. The only reason it's 4 stars is you have to open the app before stepping on for the composition metrics to register — a minor annoyance. The Fitbit sync works perfectly. Body fat readings are consistent and track well with how I feel physically. Solid buy."

For weight, the Renpho scale is accurate to within 0.2 lbs — comparable to medical-grade scales. Body composition metrics (body fat %, muscle mass) use BIA technology and are estimates: useful for tracking trends over weeks and months, not as precise as DEXA scans. Weigh yourself at the same time each day for most consistent results.
Yes. The Renpho app syncs directly with Fitbit, Apple Health, Google Fit, Samsung Health, and others. Weight and BMI data transfer automatically after each weigh-in. Body composition data syncs where the third-party app supports it.
Up to 8 user profiles can be set up in the Renpho app, each tracking their own body metrics independently. Great for families. The scale auto-recognizes which profile to assign based on weight range.
The Renpho ES-26M uses 3 AAA batteries (included). Battery life is typically 12–18 months with daily use. The scale has a low battery indicator in the app.
Renpho recommends not using the BIA body composition features during pregnancy. You can still use it for weight-only mode — step on without connecting to the app. Consult your doctor for specific guidance.
