# Algorithm Visualizer vs NSOperation

The clearest difference is in-app purchases: NSOperation at none against Algorithm Visualizer's 3. Algorithm Visualizer's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.2). On price and ads there is nothing between them.

Both are free to download. Algorithm Visualizer sells 3 one-off in-app purchases. NSOperation asks for nothing beyond the download.
