# Data Structure Display vs AlgoViz

The clearest difference is review sentiment: AlgoViz at 100% against Data Structure Display's 62%. AlgoViz also leads on rating (5.0 vs 4.5) and in-app purchases (none vs 1). Data Structure Display's advantage is ratings volume (676 vs 1) and device support (4 vs 1). On price and ads there is nothing between them.

Both are free to download. Data Structure Display sells 1 one-off in-app purchase. AlgoViz asks for nothing beyond the download.

AlgoViz holds the better App Store score, 5.0 against 4.5.
