Androzip – File Viewer

Androzip is a nice file viewer with the option to zip files as zip, gzip, or TAR. Very stable.

Pros:

Stable
Intuitive
Unique option for a handheld (zipping files)
Ability to send files in email

Cons:

No thumbnail viewer for images
No layout or view options

Works nicely in conjunction with ES File Explorer if you want to upload files to an FTP server.
