HealthKit sync is a mess – Withings Health Mate Review

The data from this app does not reliably sync to HealthKit, only showing up in fits and starts, bits and pieces. It’s not usable for that reason. Further, the scale will stop talking to the network when its batteries are low without informing you of the fact. You’ll just have to notice that you have missing data potentially weeks later by which time it’s all lost forever. That’s not helpful for keeping an eye on trends.
