GPS or Apps- What Does Everyone Use?

My apologies to SugarCubes, as I’ve derailed her previous thread enough.

I am using Road ID right now to let my husband know where and when I am out riding. The app is great for what it does- lets him know when I start, stop and can pinpoint my exact location in case of emergency. It also tracks time and distance.

I would prefer something that does not run off my phone as we get into some remote areas where battery life gets short fast.

I would like something that would also allow me to download maps, as well as track changes in altitude. I would prefer a watch type GPS, I think, as I am already carrying a full cantle bag of essentials. I have a friend who uses a handheld Garmin GPS that does those things, but again it takes up space in the bags.

Any recommendations or suggestions? Thanks!
