Loopt notes that originally the app was made for feature phones and therefore required a US phone number to register. That has changed with the new update. Now you sign up for the service using an email account. There is no charge to sign up for Loopt. Apparently, the English version of the app is what is going to all new countries.
The app will allow users to find friends, check in, meet up, and discover places. Once those places are found Loopt also allows people to share information about a place. If you aren’t familiar with the app, but are in a country that is now supported you can check out the video below to see what you are into.
