# Pipe Flow Wizard vs Pypley

The clearest difference is price: Pipe Flow Wizard at Free against Pypley's $2.99. Pipe Flow Wizard also leads on rating (4.5 vs 1.0) and ratings volume (102 vs 1).

Written reviews complicate that: 50% of Pipe Flow Wizard's written reviews are positive against 83% of Pypley's, so the app with the better star average is not the one people write more warmly about.
