# EE ToolKit vs Kmap Solver

The clearest difference is price: EE ToolKit at Free against Kmap Solver's $3.99. EE ToolKit also leads on rating (4.7 vs 3.4) and ratings volume (1.4K vs 8). Kmap Solver's advantage is in-app purchases (none vs 1). On ads, device support and iOS requirement there is nothing between them.

EE ToolKit is free to download; Kmap Solver costs $3.99 up front. EE ToolKit sells 1 one-off in-app purchase. Kmap Solver asks for nothing beyond the download.

EE ToolKit holds the better App Store score, 4.7 against 3.4. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 90% of EE ToolKit's written reviews are positive against 67% of Kmap Solver's.

EE ToolKit ships an update every 3 months, Kmap Solver every 9 months. The most recent releases landed on October 12, 2026 and October 4, 2026 respectively.
