70K Bands is an unofficial app dedicated to the 70,000 Tons Of Metal cruise band rankings. It provides a comprehensive list of all the bands scheduled to play on the cruise in February. Users can explore bands through official links, Wikipedia, and YouTube. The app offers push notifications for new band additions, detailed band descriptions by Aaron Copeland with customization options, and supports both iPhone and iPad devices with cloud integration for seamless updates between devices.

The app features offline mode for use on the ship, excluding external web links, and allows users to share their favorite bands via standard IOS sharing. Users can set up Alert Preferences for onboard activities and shows, with the ability to track attended shows for post-cruise reporting.
