OceanTrack is based on an old app I once wrote called SeaQuest; it has been revived, improved and just relaunched under a new name and a modern interface. Like all good things in technology it was born out of necessity rather than on a whim, and in particular, the need for the Witch to know her numbers and find her way safely across busy shipping lanes. There’s a lot more planned for this little app which only exists because the Witch exists and uses her as the primary test platform and proof of concept.
OceanTrack is available for iPhone and iPad on the App store, get it if you can and support its further development.
