iPhone Applications for Amver?

While we don't have an Amver application for the iPhone (yet) gCaptain recently posted a great article that had 10 useful iPhone apps for those adrift at sea. The applications were:

1. Sextant
2. StarMap Pro
3. Traveling Companion-True Compass
4. Sunrise
5. Tide Tables
6. NOAA Raster Charts
7. Foreca.mobi World Weather
8. 1st Response Emergency Kit
9. Emergency Beacon
10. Ship It!

What's the best piece of equipment to have aboard your vessel if you end up in distress? An EPIRB of course, how else will search and rescue authorities and Amver ships find you?
