Every activeLife Trainer comes equipped with a fully Android and Apple iOS compatible smart sensor operating under the Bluetooth Low Energy (BLE) standard. This makes it compatible with many fitness wristbands and any Android or Apple smartphone or tablet sold in the last few years. The BLE smart sensor implements the international open standard interface for bicycle speed and cadence so users can track their workouts on this under-desk mini elliptical exercise machine using dozens of free exercise apps such as Wahoo Fitness or Cateye Cycling. Such tracking of activeLife Trainer workouts is often key to keeping users actively engaged because, over time, the workout numbers get really impressive! Many activeLife Trainer users “walk” hundreds of miles per year burning tens of thousands extra calories.
