Train the skills, not just the moves.
There are many tools for playing backgammon. There are far fewer for practicing the underlying skills that actually make you better. Backgammon Gym fills that gap: a native iOS app dedicated entirely to structured training, not matches.
The idea grew out of my own return to serious backgammon after a 25-year break. I came back with enthusiasm but without the mental reflexes that take years to build. Decent tools existed online, but nothing felt at home on an iPhone. So I started building one — initially just for myself, but the deeper I got into the material, the more it seemed like something worth sharing.
From guided, step-by-step counting to full-speed drills. Multiple methods, multiple levels.
Pattern recognition for faster, more accurate counts. Trains the part of your brain that matters in real play.
Every board shows its GNU and XG position ID. One tap copies it — jump straight into BGBlitz, XG or GNU for deeper analysis.
Statistics and trends for each training module, so you can see where you're improving and where you're not.
Every match score has a known win probability. Train to recall the right figure instantly, or to reconstruct it on the fly when it counts.
Backgammon Gym reached a complete, working state and went through TestFlight with a small group of testers, to whom I'm grateful. These are screenshots from the finished build.
The app is written in Objective-C, targeting iPhone and iPad (iOS 16.4+). The full source code is on GitHub under GPLv3.
Active development has stopped, but the code stays public. Anyone is free to fork or port it — including to Android — as long as it stays free in the store. If you'd like to pick the project up, open a discussion.
