phones & apps & computables

After many time finally i finally re- purchased a smartpho(e)ne(ix). It's the Moto 4G and I feel giddy. The last smartphone I had, the Iphone 3g, was smashed on a radiator

purposefully

repeatedly

by me

back in 2011, right before the time in which i secluded myself from the scary world and hid myself in dark- and aloneness.

Behold, my new smartphone. It is a delicate thing of beauty.

After being away for 4 years, I feel pretty n00b in smartphone land.
What are some essential apps to have? Whatsapp is the main reason why I buy this thing: because that's how my friends stay in touch these days. Heard things of Tindr, ofcourse. But other than that I am unknowledgeable on the this's 'n thats. What other cool things can a smartphone do?

Basically I'm interested what smartphone land is in 2015.
