Six apps and trackers to find your lost gadgets

Finding yourself out and about without your smartphone can make you feel naked. We rely on these devices so much that losing them creates a huge problem, preventing you from messaging friends for aid or mapping your way back home.

Losing any similarly essential device, like your laptop, creates an equally huge headache. To rediscover these lost gadgets, we've collected tech that finds your tech. These six apps and trackers can plot your devices on a map, force them to make audible sounds, and perform other tricks to help you reunite.
For Apple: Find My iPhone/iPad/Mac
Apple wants you to keep its devices safe, and to that end, it built a phone and tablet tracker into iOS and a laptop finder into macOS. Enable the feature on all your Apple hardware, and you'll be able to see the current location of any device on a map.

To set it up on an iPhone or iPad, open Settings and tap your Apple ID at the top. Then pick your device and select Find My iPhone (or Find My iPad) to switch on the feature. On a computer, open System Preferences and click iCloud. Then tick the Find My Mac box. During this process, Apple may prompt you to sign in with your Apple ID credentials, so make sure you have your password close to hand.
Once you've enabled the tracker, you can forget about it until you need it. If you do lose a device, grab your remaining machine(s) and open the appropriate app: Find My iPhone on a phone, Find My iPad on a tablet, or the iCloud web app in any browser window. Sign in, click the All Devices menu, and pick a device to see its location on a map. Within this app, you can also select a device and prompt it to make a sound, lock itself, or erase all its data.

The lock option is particularly useful because you can make the lost device display a custom message. For example, if you lose your iPhone, make the gadget share a message requesting its safe return and providing an email address where finders can contact you. And to prevent those finders from snooping further, locking the screen will protect your data.
For Android: Find My Device
Like Apple, Google has included device-locating tool, called Find My Device, on Android. To enable it, open Settings and tap Security & location. Turn the feature on to start tracking your phone or tablet. Then install the Find My Device app on a backup phone or tablet.

To see where your gadget is, you have a few options. Open the app on your backup device, visit the Find My Device web portal, or just sign into your Google account and then type "where's my device?" into the search engine. As with the Apple service, you can make the lost machine play a sound (even when it's in silent mode), lock the device while its screen displays a message, or completely erase your information. Check out a map to view its last known location, battery level, and even the name of the Wi-Fi network it's currently connected to. Based on this information, you can decide whether it's gone forever or still can be retrieved.
Unfortunately, Google doesn't offer similar protections for Chromebooks—at least for the time being. So if you lose one of these Chrome OS-powered laptops, you won't be able to find it through Google. However, keep reading to learn about a third-party app that may be able to do the job.
For Samsung: Find My Mobile
Samsung owners can use the aforementioned Google tracker or Samsung's built-in Find My Mobile tool, which works very similarly. To access it, first set up a password-protected Samsung account.
Next, enable the tracker by opening Settings, tapping Lock screen and security, and choosing Find My Mobile. On this menu, make sure to toggle the Remote controls switch to On so that you can operate your phone or tablet from another device.
If your gadget goes missing, head to the Find My Mobile website and sign in with your Samsung credentials. Here, you can check out the last known location of your phone or tablet on a map. Like with the other tracker apps, you can ring your device even if it's
