Score breakdown
Our verdict
Choose the ScanWatch Nova (DriftScore: 82) if you want comprehensive health tracking throughout your day - its 30-day battery life and luxury design justify the $599 price for serious health monitoring. Pick the Body Scan (DriftScore: 77) only if you specifically need segmental body composition data and nerve health assessment, as $399 is steep for a scale that you'll only use once daily. For most buyers, the ScanWatch Nova delivers better value despite costing $200 more.
Frequently asked questions
Which has better ECG accuracy?
Both offer medical-grade ECG with AFib detection, but the Body Scan uses a 6-lead system versus the ScanWatch Nova's single-lead ECG. The Body Scan technically provides more comprehensive cardiac data during the brief measurement period.
Can I use both products together?
Yes, both sync to the same Withings Health Mate app and complement each other well. The Body Scan provides detailed morning metrics while the ScanWatch Nova tracks your health throughout the day.
Which is better for weight loss tracking?
The Body Scan excels here with segmental body composition showing muscle/fat changes in arms, legs, and torso separately. The ScanWatch Nova only tracks activity and doesn't measure weight or body composition at all.
