# EE ToolKit vs VoltLab

The clearest difference is update cadence: VoltLab at every 4 days against EE ToolKit's every 3 months. VoltLab also leads on rating (5.0 vs 4.7). EE ToolKit's advantage is ratings volume (1.4K vs 363) and iOS requirement (12.0 vs 15.0). On price, review sentiment, ads and in-app purchases there is nothing between them.
