The Shabbat Shalom application will allow you to quickly check the candle lighting times, havdalah times and parsha for the week in any location in the world. This comes in handy when you quickly want to know when Shabbos is or if you want to know if it is too late to call your in-laws in Israel. Just flip through the different cities and countries, to see what the local time is and what time they start or finish Shabbos.
