What is your favorite Islamic app for smartphones?

Please share with me your favorite Islamic app. Mine is Muslim Mate for iPhone and iPad as it is a very comprehensive app covering all the five pillars of Islam and is a really good companion. Here's its screenshot. You may as well share the screenshots.

One of my favorite is Salatuk for ios and android. It gives prayer timings for your location.

Mine is iSubha. Touch prayer beads, well worth getting .
