My Experience With FitTrack Pro 8X
After testing the FitTrack Pro 8X for several weeks, it became clear why it sits at the top of our list. The setup was incredibly simple, and the app synced instantly every time I stepped on the scale.
Compared to other scales we tested, the consistency of the 8-electrode BIA technology stood out. Most home scales use only 4 electrodes, which can lead to larger fluctuations. The Pro 8X felt professional-grade.
