Verdict

The call

The clearest difference is price: EE ToolKit at Free against Area and Volume Calculator's $1.99. EE ToolKit also leads on review sentiment (90% vs 60%) and ratings volume (1.4K vs 2). Area and Volume Calculator's advantage is in-app purchases (none vs 1) and iOS requirement (8.0 vs 12.0). On rating, update cadence, ads and device support there is nothing between them.
