Long time reader, first time poster :)
I have made an app, which works as an international taxi directory and I hope it could come usefull for at least several of you ;)
Main features:
Supports all towns and cities of over 5000 inhabitants,
Auto detects your location,
Lets you add your own numbers, or import them directly from the phonebook,
Functions offline using numbers youve saved or downloaded,
Has a user-friendly, ad-free interface that follows Windows Phone Metro design principals.
