Finally I finished one more app. I don't have much time, so it took me a lot of time to implement it. However, I think it's really cool, and definitely easy to use..
I named it "Emergency Phones" and it includes three types of emergency telephone numbers (Police, Fire, Medical) of 124 countries from around the world. You don't have to search for the country you want, you just start the app and in a few seconds (2-11) it gives you the numbers of the country you are currently situated. So simple!
It will be released in approximately one and half week, if things go as planned; nevertheless I am prepared for a slight delay, due to the iTunes Connect "Holiday Shutdown".
