What are the best apps to use?

[Allan Edmond]

Hello BP, I've been looking @ this site for a couple of months now and decided to join for the new year. In my 1st post I would like to share the apps I use and find out what apps BP members are using.

1) sign my pad- sign docs from your tablet or phone.
2) foxfi- free internet hotspot.
3) cam scanner- takes pic of doc and saves it as a PDF to your computer.
4) dropbox- gives you access to your docs anywhere via the cloud first 2gb are free.

I need a good office suite to read and make exel docs if anyone knows one.
Also I need an app that edits PDF files. Thanks in advance
