Google Maps, the navigation app that's preloaded on most Android smartphones (at least, those which comply with Google's Mobile Application Distribution Agreement), is one of the most popular on the planet. It's the go-to source of directions, restaurant recommendations, photos, and business hours for more than a billion users worldwide, and it's no wonder; to maintain its Sterling reputation, Google says it makes "millions" of updates to Google Maps every day.

But there's a lot about Google Maps that isn't obvious, which is why we've compiled a list of some of the less-obvious features lying just beneath the surface. Master them, and you'll be well on your way to becoming a Google Maps power user.

How to Measure the Distance Between Points

When you're zoomed out to 1:12,000 scale (1000 feet, represented on the map by 5.28 inches), every destination looks like a just a hop and a skip away -- until you start walking there. To find the true distance between two points, use the measuring tool in Google Maps. It's easy:

  1. Touch and hold anywhere on the map. You'll see a red pin appear.

  2. Tap the name of the place at the bottom of the screen. Scroll down until you spot the Measure distance tool; tap it.

  3. Move the map until the black circle is hovering over your destination. You'll see the distance in miles (or kilometers) at the bottom.

  4. Tap the plus button to add more points, or select the three-dot menu icon to clear your selections.

How to Download an Offline Map

We might live in a world of 24/7 connectivity, but offline maps have their uses -- whether you're planning a road trip through the backcountry or closing in on your monthly data cap. Luckily, they're easy to download, store, and manage in Google Maps. You just need to know where to look.

  1. Search for an address, town, or city, then tap the location's name at the bottom of the screen.

  2. Select Download. You'll find it next to the Share Place button.

  3. Drag or zoom to adjust the map, and then tap Download.

  4. Maps will download the area in the background. When it finishes, you'll be able to search for businesses, see street addresses, and get turn-by-turn directions even when you aren't connected to Wi-Fi or cellular.  

To manage the maps you've downloaded, swipe left from the Google Maps home screen. Tap Offline maps, and select the three-dot icon next to any map in the list to Update, View, Rename, or Delete it. Alternatively, select the gear button in the upper-right corner to tweak offline maps' behavior. You can prevent maps from automatically updating and downloading, or specify whether you want offline maps to download over Wi-Fi, cellular, or both.

How to Search Along A Route

Need to find a pit-stop in the middle of a road trip? Google Maps lets you search for gas stations, restaurants, coffee shops, and everything else your heart desires en route to your destination. It couldn't be simpler:

  1. After you've started turn-by-turn navigation, tap the magnifying glass icon in the upper-right corner of the screen, below the microphone button.

  2. Type in a destination, or choose from one the suggestions (Gas station, Restaurant, Grocery stores, Coffee shops).

  3. After you make a selection, you'll see the names of nearby places along your route, in addition to the estimated amount of time they'll add to your commute.

We've all been there: You made a spur-of-the-moment plan to swing by the hip new restaurant in town without a reservation. Wouldn't it be nice if you could see when it's going to be least busy? Good news: With Google Maps, you can. Google crowdsources anonymized location data from Android an iOS users to predict how crowded a place will be at any given time.

  1. Search for or tap on a restaurant, theater, bookstore, or other venue in Google Maps. Tap on the name at the bottom of the screen.

  2. Scroll down until you reach Popular times  -- it should be below Questions & answers. Not all locations are tracked.

In addition to an hour-by-hour crowd report by day of the week, Popular times shows how long you'll likely have to wait and how long people usually spend at the location.
