So I just bought my first Android phone , any suggestions?

As the title states, i've just purchased my first Android phone!

I got the white 32gb nexus 5. I've been an iphone user (since the 3g) and I do own a few macs. I just received my Nexus 5. I'm pretty stoked about it . After reading many reviews I decided to pick one up.

I'm not going to lie , it is a little hard transitioning from the iPhone/ mac ecosystem to Android but I must admit I do like KitKat.

I've found the widgets particularly handy but I as also kind of disappointed with the google play store. Haven't seem to find any outstanding apps. Anyways , I was just wondering if you guys had any ideas to share. Any cool features , apps.

It would be greatly appreciated ,
