From Iain Munro:
iFIND Canadian Golf Course Finder (Lite Edition) shows you the nearest three Canadian Golf Courses to your location.Open the iFIND Canadian Golf Course Finder (Lite Edition) App and it displays the nearest 3 golf courses to you. All locations include a name, address and phone number. Tap the phone number to dial (iPhone). View the map to see exactly where you need to go. The data is stored locally, so you don't need to find a Wi-Fi connection or use expensive cellular data. (Only the map uses the network.) If you have some good or bad points to share about a particular golf course, there is a link to send in the details, which will be included in future database updates.
