This pre-loaded and free app from iPhone users has saved my own ass as well as my friends too many times to count. While most people think it’s “creepy” to be able to know where all of your friends are just by looking at the app, it is actually extremely convenient and can be helpful for nights out on the weekends.
Before you say "no way, I don’t want every one of my friends to be able to find my exact location any time they please," remember that you have to allow people to follow you first and you can choose only specific people to be able to see where you are located. You can also turn off your location even for your followers at any time so nobody can find you. It’s really not as creepy as some may think; it is so convenient that my friends and I use it all the time and for good reasons. The app can not only use its GPS locater to locate the person or people you want to find, it will also use the GPS in maps to get you there.
In a serious situation, the app is especially useful. My friends and I use it to be sure that if one of us were walking, especially at night or on a weekend, that they made it home safe. If we lose track of someone on the weekends and they aren’t answering their phone, we are able to locate them using "Find My Friends" in a matter of seconds. This app can seriously help in situations where if someone is left alone and are potentially unsafe, they don't even have to be on their phone or calling us physically for us to find them. It can also be useful to be able to track your own phone from someone else’s to see where you left it the day or night before and be able to retrieve it.
This app may seem quite stalker ish or that it would be uncomfortable to know that your followers can look up your location at any given time, but it really can be helpful in safety situations where your friend is lost or not answering or for convenience to see if your friend is at home or work and if you can stop in. This app is seriously a life-saver and my friends and I use it religiously for good reasons, and if your friends have a tendency to get separated from the group easily, this is what you need for them.
It's also nice to know, when you have the app and others are able to locate you, that if you ever were to be in an unsafe situation or if you find yourself somewhere alone that your friends would be able to find you if you needed very quickly without you even having to text them.
