# OpenGL ES Reference vs Shor's algorithm

The clearest difference is in-app purchases: OpenGL ES Reference at none against Shor's algorithm's 3. OpenGL ES Reference also leads on iOS requirement (8.1 vs 16.0). On price, ads and device support there is nothing between them.

Both are free to download. Shor's algorithm sells 3 one-off in-app purchases. OpenGL ES Reference asks for nothing beyond the download.
