The two apps I can’t live without

If there’s one common quality among most smartphone apps, it’s that they tend to focus your attention inward, to the exclusion of the outside world. Two of my favorite mobile apps, though, take advantage of your phone’s camera so you can get even more out of the world around you. 

Using augmented reality, these apps let you point your phone’s camera at various objects to learn more about them.

A lot of this functionality is being built into more modern Android devices and iPhones — for example, the iPhone’s camera app can now identify dog breeds as well as plants, and both Visual Look up and Google Lens also provide a lot more context about what you’re seeing through your smartphone’s camera. 

But there are still a few things phones can’t do on their own just yet. And that’s where these apps come in. While they didn’t make our list of the best AR apps, they’re still worth a look.

Best of all, both apps are available for Android and iOS phones, so you can use them regardless of the device you own.

My home happens to be near the flightpath of both Teterboro and Newark Liberty International airport, so there always seems to be a plane soaring overhead. As a longtime plane geek, I always wonder about the aircraft, and where it’s going. 

Flightradar24 lets me see all the minutiae of every plane that flies by — where it’s going, its altitude, speed, arrival and departure times, and even photos of the airplane. But what I really like about Flightradar24 is its AR feature. 

With AR turned on, I simply point my phone at any airplane in the sky, and I can see all that information at a glance. It’s fun to see a plane heading off to, say, Milan or Frankfurt and imagine being on the flight myself. Sadly, it only tracks civilian aircraft, so you can't see when Air Force One is flying by.

Flightradar24 is free, but offers two upgrades: A $9.98/year subscription removes ads and includes more aircraft details and flight history, while a $34.99/year subscription adds aeronautical charts, weather layers, and more. But, you’ll get plenty out of the free version.

When the Sun goes down, I also look to the skies to see what celestial bodies I can spot. While the New York City-area is plagued by a lot of light pollution, the Star Chart app is great when you head out into the country. As Carl Sagan once said, there are billions and billions of stars, and I don’t know the first thing about them. 

Like Flightradar24, once you open the Star Chart app, you simply point it at the sky to see what’s out there. The app uses your location data to fix your point on the Earth, so that when you look at the app, you’re seeing the stars in front of you. 

Click on any celestial body, and you can get more information about it, such as its name, distance, and the data to find it if you have a telescope. In addition to stars, it also can identify planets, satellites, and meteor showers. 

The app is free, but add-ons for meteor showers, satellites, and the extended solar system are each one-time $4.99 purchases.
