From the developer:
This is the original version of NavigX which has now been updated to use the App Store instead of being available as a download from our site.
The purpose of this release is to provide an App Store version of NavigX for minimal cost until v2.0 is released in the very near future. NavigX v2.0 will retail in the UK for £8.99 and will include all the features of NavigX for iPhone and NavigX for iPad.
