# Sketchalyze vs Eng Dynamics

Sketchalyze and Eng Dynamics both sit at 5.0 stars, but that hides the real split: 100% of Eng Dynamics's written reviews are positive against 60% of Sketchalyze's. Eng Dynamics also leads on iOS requirement (9.0 vs 15.6). Sketchalyze's advantage is monetization model (free vs freemium) and ratings volume (7 vs 1).
