Well, we all have our app favorites. I admit that I am not an App fanatic per se, neither for my Windows Lumia 1020 nor for my new ASUS Windows 8 home laptop. I use the major Social Media Apps, like Twitter, Facebook, LinkedIn and a few others. I use a few camera Apps for the awesome 41 Megapixel Camera on on my Lumia 1020. I like some news Apps, Musixmatch (better than Shazam, sorry!) and a few others, but my new favorite is a police scanner called 'Police Scanner 5-0'. It has 'police' in the name, but also it covers fire + EMT. They cover a lot of areas in the USA and throughout the world. Sometimes you hear sirens in the distance and you just have to find out EMS, police or fire fighting information! Or you just tune in to a local service or elsewhere for curiosity sake! Great fun.
