The Bad Elf GPS accessory is compatible with all location-based apps available in the App Store. However, there are two important factors to consider when determining whether an app will perform up to expectations on your iPod touch, iPhone, or iPad:
Look for apps that have an "offline" mode, include local map storage, and/or cache location data for uploading when you do have a Wi-Fi connection.
If your favorite location-based app does not list the iPod touch as a supported platform, ask the developers to include it in their next release so that you can use it with your Bad Elf GPS.
We started a list of free and paid apps with offline support that work great with the Bad Elf GPS for a variety of activities (navigation, geocaching, mapping, etc). Please let us know if your favorite app isn't on the list so we can add it!
