My only coding experience is with SAS (Statistical Analytical Software) so this article is entirely over my head. What I'm looking for is an app that would let me print the moves of a single game PGN text each on it's own line. If you created an Android or iOS app that did this, I'm sure you'd have plenty of customers. You could have a version for $2.00 that would handle single game PGNs and one for $5.00 that would handle multiple game PGNs.

What I'd want is to be able to import the PGN into the app and have it create a plain text file with the header information then the moves each on their own line that you could save to your device or to a folder on the cloud. I would import that file into a spreadhseet and use the adjacent column (widened) to enter my comments. Mostly I'd just print it so I could play the moves over the board and check them off as I went along. This would be so good for playing over classic games that weren't annotated before reading the annotations.
