Nice!
1- Keychain, security first! And for the little swap I do, it’s perfect.
2- PeakD, no other is that good for writing.
3-Worldmappin, of course, map on the website is soooo cool.
4- Hive engagement, It's not that popular but I love it, I use it a lot, it's a great way to see the interaction between two users and check all the comments exchanged.
5- Actifit, Im so into counting steps and walking, this one fits great to me.
