Frequently Asked Questions

CF661 vs CF669 — which should I choose?
Functionally identical for body composition measurement. Choose by size: CF661 is square 30 × 30 cm with a slim 31.5 mm profile (fits tighter spaces). CF669 is rectangular 33 × 30 cm with a 46.5 mm profile (more presence in the room). The CF661 also has a colour display where the CF669 has a standard LED.

How accurate is body composition measurement?
The 8-electrode design is significantly more accurate than typical 4-electrode consumer scales. Manufacturer reports ≥98% body fat correlation with INBODY 270 (clinical reference). For best results, weigh yourself at the same time of day, on an empty stomach, with empty bladder.

Does it sync with Apple Health or Google Fit?
The scale syncs natively to the Unique Health app. Onward sync to Apple Health, Google Fit, or other platforms depends on Unique Health app's integrations — check the app's settings after pairing.
