Quick Verdict

The RENPHO Smart Scale delivers more health data than bathroom scales costing five times the price. 13 metrics including body fat percentage, muscle mass, bone mass, visceral fat, and metabolic age sync automatically to your phone via Bluetooth.

13 Body Metrics

Weight is just the starting point. The RENPHO measures body fat percentage, body fat mass, lean body mass, skeletal muscle mass, muscle mass, bone mass, water percentage, protein, BMI, BMR (base metabolic rate), metabolic age, visceral fat level, and body type. Tracking these over time reveals fitness trends that weight alone misses.

App Integration

The RENPHO app shows trend graphs, health goal tracking, and historical data. Automatic sync to Apple Health, Fitbit, Google Fit, Samsung Health, and MyFitnessPal means all your health data joins the ecosystem you already use.

Accuracy

Bioelectrical impedance body fat estimates are directionally accurate — they show trending changes well — but the absolute body fat percentage can vary from DEXA scan results. Use RENPHO data for trend tracking rather than as gospel measurements.

Who Should Buy This?

Anyone tracking body composition as part of a fitness programme. The price-to-data ratio is unmatched — nothing else at £30 gives this much health insight.

Frequently Asked Questions

How do multiple family members use the same scales?
The RENPHO app supports unlimited user profiles. Each person downloads the app and logs in with their own account. The scales auto-identify users by comparing the weight reading to known profiles.
Are the body fat readings accurate?
They're consistent and useful for tracking trends — a 2% improvement over 3 months is a meaningful result. Absolute accuracy varies from DEXA (the gold standard) by 2-5% typically. Don't fixate on the absolute number; focus on the direction of change.
Does it need a subscription?
No — the RENPHO app is free with no subscription required. All features work without paying anything beyond the one-time scale purchase.
