Katana

Katana looks just like a cardholder, except this handy safety device has three ways to trigger an alert and notify the authorities. Attached to the back of your phone, you can either pull the red tab on the device or wear the $149 Katana from your wrist with your phone attached and drop the entire device to trigger an audible alarm and notify the police. The third option is to push a silent alert button three times or hold it down for three seconds to notify a 24/7 response center discreetly. We reviewed Katana and tested the multiple ways the device alerts your contacts.

Available in ten colors, Katana will blend in with your phone and not draw too much attention.

Apple Watch

The Apple Watch 8 may be a staple in your everyday life, but did you know the gadget also has emergency services? With an accelerometer and a gyroscope, the Apple Watch, which starts at $399, can detect a fall and ask whether you need emergency services. If you're unresponsive after a minute, the call will be automatically placed, and your emergency contacts will be notified.

Similarly, the Emergency SOS can also be triggered on the Apple Watch — 911 will be called, emergency contacts notified, and your Medical ID badge will be displayed on the screen.

A new feature added to the Apple Watch 8 is Car Crash Detection which can detect when there has been an accident in the car. Once detected, within 10 seconds, your watch will contact emergency services to notify them of the crash and provide your location. This feature is only available on Apple Watches with watchOS 9 operating systems and works only when driving. Which Apple watches can get watchOS 9? Apple Watch 5 and later can upgrade to watchOS 9.

Tile

Tile is a must-have for me, and the $35 Slim model, which GearBrain reviewed, is a thinner, more discrete version of the original look — perfect for sticking in thin wallets or sleek laptops. With the Tile app, one tap of your smartphone will let you know the location of your expensive devices, so you can keep them safer whether in a hotel or even in an Airbnb abroad.

Bluetooth Headphone Adapters

​When traveling this Spring, you should also bring an airplane Bluetooth headphone adapter. This little device will allow you to connect your wireless Bluetooth headphones or earbuds to the airline's in-flight entertainment system. This small device plugs into the socket of the seat-back entertainment (or sockets if the plane has one for each left and right channel), then broadcasts the sound over Bluetooth. They are a must-have if you want a quality sound experience while in the air.

These Bluetooth adapters range in price from as low as $16 to over $50 per device. You can learn more about these smart travel devices by visiting our review: Five top airplane Bluetooth headphone adapters.

Life360

Letting your family know you're safe is never a bad move. Life360 is an iOS and Android smartphone app that allows families to keep track of each other in case of emergencies — and it works overseas, tapping into any Wi-Fi connections and pinging the last known location. Your parents can see your location with the Life360 app instead of texting you every hour, and they can even instantly message you or have a group chat to ensure you're okay. There's a free version, which allows you to input two known locations, so you know if someone has arrived home, and a Gold Membership for $14.99 a month or $99.99 a year, which lets you set up unlimited places in the app.
