The Disc Golf Mapper app is an essential companion on the disc golf course and packed with many convenient features. The game feature quickly keeps score for each hole and lets you post game scores on Facebook. High contrast graphics make the screen easy to see outside. The map feature shows course maps to help you find the next hole. Course maps can be shared with other players. The map editor lets you mark tees and baskets as you play the course by tracking your location. Then share the course map with others. Also invite Facebook friends to play a game of disc golf.

As of 8/6/2013:
All known course issues have been resolved. If you have difficulty accessing a course, contact support (discgolf@freemanscience.com)

We currently have an issue supporting users from Finland, but hope to resolve this issue. If you have difficulty creating a screen name contact support.

The app does not come with course maps for all areas, but lets you create maps and share with others in your area. Map coverage is high in Austin, TX (because I live there).
