And which applications on android phone do you use?

I use only 12 applications and two widgets on android, probably there are some other interesting features that I do not use.

1) LastPass - online password store, well of all hands.
2) Barcode scanner - I scan mostly qr-codes, occasionally glands on the inventory.
3) Skype - for calls and chat.
4) Gmail - Google Mail aggregates all my emails instituted in my life.
5) Google Reader - A few years ago, I aggregated all incoming information flows from outside, except for twitter.
6) 2GIS - Map of the city, bus routes, restaurants and much more, and everything is available offline (this is its main advantage).
7) Google and Yandex maps - I use it to view satellite images of the terrain.
8) Advanced Task Killer - killing all sorts of applications to save battery.
9) Twitter - for posting to Twitter and reading the tape.
10) Google docs - to work with your documents.
11) Quick wifi - for quick sharing of 3g internet via wifi.
12) Flashlight - can shine flash, screen, blink and pretend to be a police flasher.

Two widgets:
1) Weather online.
2) Control via click for bluetooth, wifi, brightness, update, gps, etc.
