Pocket METAR 0.82

the author of this app says:

This is a multi-function program for GA pilots that want to keep track of weather reports at different airports. If you have a wireless jacket you can download new METAR reports instantly and the software will sort and store them under the correct airport in its database. It can also calculate the side-wind component for you, just pick an airport and what runway to use and if a METAR report has been received it will calculate the side-wind component.
