We use life360 for this. I can see where my wife is, I can know when she arrives home safely. She gets a notification when I leave work so she knows I'm on my way home to help with the kids.
For younger children, it's hard to object. But the general idea that you might give general access to your location info to a family member and that not doing so could become an issue feels... bothersome.
In a different vein, as someone who grew up pre-cell phones, I'm a bit bothered by the idea that you should always be reachable. That said, as satellite trackers/SMS/emergency beacon devices become more affordable I do start to ask myself if something like this isn't prudent on a relatively remote solo trip.
I've seen this in Life360. Have you found youself in situations where you want to share with others outside your circle? Ex. People who don't have Life360 installed.
I was using this app but it seemed like it drained the battery so me and my SO got rid of it. :\ It was super useful though, but couldn't get pass the power drainage.
As an engineer at Life360, I can tell you that we hear you loud and clear. We haven't always been the best at achieving high accuracy _and_ power efficiency, but we are improving the technology dramatically. Battery drain has been a major focus for our engineering team for a long time, and especially recently. Give it a try again and let me know how your experience is.
