I purchased an eufy scale partly based on its association with the Anker name (something they proudly displays all over eufyLife ). When I read that there was a sign-up step to configuring it, I was a little worried that it was another cloudy ploy to collect marketing information, but was pleasantly surprised that they offered a guest mode which doesn't require sign-up. Unfortunately, it won't share data with apple health without sign-up. I'm not sure if this is an apple-enforced app sandboxing, but I have other apps that can.
Just now, looking at my phones battery settings, I found that eufyLife had been active for 2 hours and 55 minutes with only one minute of that being because it was in the foreground. What exactly is it doing when I'm not using it?
All in all, I'm a little worried about privacy incursions. I like the functionality, but it seems to be busy with more than I've asked for, so it's officially on probation.
