I can see how the popularity of these Apps are going to grow as more and more people get smartphones.
The Fortification of a Muslim and Masjid Finder applications seem particular apt (pun intended) for those on the go.
On a flip note, it is kind of scary that there is so much more information / resources available to us nowadays and the excuses for inaction grow fewer by the day!!
PS I’m still waiting for the official Jannah.Org App
