# Sketchalyze vs ONELAB

Sketchalyze and ONELAB both sit at 5.0 stars, but that hides the real split: 100% of ONELAB's written reviews are positive against 60% of Sketchalyze's. ONELAB also leads on update cadence (every 2 months vs every 13 months) and iOS requirement (9.0 vs 15.6). Sketchalyze's advantage is ratings volume (7 vs 1).
