How can I tell if an app is safe to use?

When using devices like smartphones or tablets (such as an iPad), apps are essential. If you're unfamiliar with the term, "app" is short for "application." It refers to any software designed to perform specific tasks. Whether it's a game, a show-streaming service, or a weather tracker, it's an app when used on mobile devices.

While devices come with a few preinstalled apps, there's always room for more. To explore additional apps, visit a digital distribution platform, which varies depending on the device. For Android users, Google Play (formerly Android Market) is the go-to place, while iPhone users head to the Apple App Store. There are also third-party platforms, like the Amazon App Store, that are not tied to a mobile provider.

With so many apps available in the stores, it can be hard to decide which to download. For example, in the Google Play Store, there are over 500,000 apps. As an insomniac, I once searched for apps claiming to hypnotize me to sleep, and found 180 options with prices ranging from free to $4.99. Independent developers can publish their apps on these platforms and earn a portion of the sales. So how do I choose the right one? My primary concern is always app safety.

While many people are cautious about opening email attachments from strangers, they may unknowingly download apps without considering the risks. Some apps can be harmful—they may carry viruses, worms, malware, or other threats. These apps could steal personal data, contacts, or passwords and share them with malicious parties. Thankfully, there are precautions you can take to avoid such threats.

How to Ensure Apps Are Safe

The first essential step to securing your apps is by installing security software. Just like on your computer, your phone needs protection too. Basic security apps will scan for suspicious activity, but there are advanced options that let you track your phone's location or even remotely erase data if it’s lost or stolen. While some features may require a paid subscription, most security software costs less than $40 annually, a small price to pay when considering the potential damage from things like stolen credit card information.

Now, how can you be sure the security app you’re considering is reliable? Research is key. I found my security app by searching online for reviews and expert recommendations for Android phones. Most download platforms feature customer reviews, which can guide you after you’ve narrowed down your options. However, be cautious—if every review sounds overly positive and uses similar wording, it could be a sign of fake reviews. Some developers hire people to leave glowing feedback to artificially boost their ratings.

Also, investigate the app's developer. Many developers have official websites, and you can see a list of their other apps. Large, well-established game publishers, for example, are unlikely to create malicious apps. It's safer to stick with well-known platforms associated with your device's operating system. These platforms implement screening processes to assess apps before they are listed and can quickly remove harmful apps.

After selecting an app, review the permissions it requests before hitting download. Some apps may ask for access to your location, phone call details, or the ability to modify data on your SD card. Think carefully about whether each permission is necessary for the app's functionality. For example, an app that helps you find nearby restaurants needs your location, but does a list-making app really need that information? While the app asks for permissions, it’s really telling you what actions it will take, and the choice to accept or deny is yours. Refer to the sidebar for some common permissions to watch out for. By following these steps, you can avoid the most dangerous apps and ensure the ones you already have remain secure.
