# EE ToolKit vs Complex Calc

The clearest difference is in-app purchases: Complex Calc at none against EE ToolKit's 1. Complex Calc also leads on rating (5.0 vs 4.7). EE ToolKit's advantage is ratings volume (1.4K vs 2) and update cadence (every 3 months vs every 6 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. EE ToolKit sells 1 one-off in-app purchase. Complex Calc asks for nothing beyond the download.

Complex Calc holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 2, so its average is the more settled of the two.

EE ToolKit ships an update every 3 months, Complex Calc every 6 months. The most recent releases landed on October 12, 2026 and October 2, 2026 respectively.
