Gaia GPS has become a useful easy field app if you have an iPhone/mini-ipad. Don't know if it has an Android version. Lots of map choices, crisp seamless topos which you can layer over high-quality satellite, and toggle in gradations back and forth. A cheap subscription gets access to the best maps. Can't get all of Soyo in one download but you can get all of Chiquito Ridge, say. I think the combo helps cross-country. Requires the usual battery conservation practices but I like the interface and screen better than I liked my Garmin, easier to scroll. For roads, I use the Sierra National Forest App, which is a straightforward forest road map and free, I think.
Sorry to say I've probably spent ten times as many hours on Google Earth daydreaming as I've spent climbing.
