Since we are obviosuly getting close to 2013, I was just wondering what everyone favorite apps of 2012 were? Matters not which device/OS you have! My personal favorite is Instagram. It's a really nice and fluent app. It's much better than any other social network in my opinion, and I love the fact that you can explore everyones elses photos (mainly just food... )
Bad Piggies is the sequel to Angry Birds and has the pig bad guys making machines to gather map data. It's inventive and fun to play.
BSPlayer - free video app for Android so I can watch vids (including .mkv vids) on the go (downside is that you have to pay to get rid of ads and only when I use Wi-Fi which I never use)
