With most of us now using phones for GPS when driving, walking, biking, etc., it’s important that a map app is reliable and accurate. This one is the standard and it’s still pretty good, with plenty of regular updates. Maps does let you choose from a couple of routes to take, instead of just being stuck with whatever the app thinks you should do. Since you often just need Maps as a guide, rather than for somewhere you’ve never been, this is a key option. The app isn’t as flexible as the web version for you to make individual changes in your route, but having a couple of options is better than none.
For Android, Street View is nested within the “regular” Google Maps app. If you search for an address, when it comes up, long-tap on the pin and street view will pop up below. Click on the picture to make street view full screen. Then use the white arrows to go up and down the street, turn corners, etc. To look around, use your finger to turn around and see across the street or down the road. Or use the panorama button with the arrows going in a circle to pan around slowly. Sliding fingers together moves you out (more overview), sliding fingers apart zooms in.
