Plip

This app aims to simplify location sharing for all ages, and because it never uses an internet connection it is completely secure too. This makes it ideal to find out the locate/track children and old family members, as they might not necessarily have an internet connection or want to handle a complex-looking application. The app also doubles up as an SOS application in times of emergency.

The app necessarily sends a Google Maps link to all the numbers selected from your contacts list, so the reciever of these location messages is required to have an internet connection.

This app and the concept of being used for women and children safety happens to be the winner (under the Pebble Smartwatch Category) at HackIndia 2015, a national level hackathon.

Make sure airplane mode is turned off and you have enough balance to send the SMS. Also for maximum location accuracy it is recommended that your GPS is switched on while using the app. Pebble users are required to keep atleast one form of location service switched on,even if the app is not on, so that the app can obtain location in the background.

Also, before using the app for it's intended purpose please do chose contacts from your contacts list to whom you would want to send your location to.

The app also happens to be compatible with the Pebble smartwatch, so sending your location can be done through your smartwatch without taking out your phone, again, making it ideal for situations of emergency or threat.
