Companion: Never Walk Home Alone
While many larger companies have sophisticated security offerings for their travelers while overseas, some smaller companies don’t have the means to offer such tools. While Companion was designed for the college campus environment, it works very well as a security device for travelers.
When traveling in an unfamiliar environment, you can enter your destination in the app and select a contact to notify of your route. The app will notice any deviations or unusual movements in your route and if you don’t confirm that you’re OK on the phone, an alarm will sound and your selected contacts will be alerted. Throughout your journey, your contact can see your route, live on a map. The service uses data and while some travelers are very judicious with their roaming data while traveling, providing safety and peace of mind is likely worth the additional data roaming charges.
The app is available for free in the Google Play and iTunes stores.
