Go Grinder
GoGrinder is a program for practicing Go problems. The iPhone version is now available in the iTunes store, and is the only app that lets you use your own problem collections. There is also a Java version for desktop computers.
GoGrinder uses problems in SGF format. 347 problems are included in the install, and thousands more are easily downloadable. GoGrinder can import the archived problems from goproblems.com, and sort them by type and difficulty (see docs for instructions). Converting problem books to SGF is an excellent source of material for GoGrinder. Recommended books include Graded Go Problems for Beginners, Get Strong at Go, and Mastering the Basics.

Troubleshooting
RichardHunter: I had trouble using GoGrinder 1.14 on the Macintosh, but I found the solution. Trying to split an sgf collection seems to fail. There is an unintuitive trick to it.
Problem: You want to split an sgf collection file. Use the Split File icon to select the file. This seems to work. You are asked for the destination folder. Whatever you select, you get the Error Message: "The destination must be inside problems directory." This message appears even if you do select a destination inside the problems folder.
This implies that the trouble is related to the destination. Actually, the trouble is the location of the source file.
Solution: The file you want to split must be in the problems folder. Move it there before you try to split it. Create a destination folder inside the problems folder. Now split the file and the individual sgf files will appear in the destination folder.
