# EE ToolKit vs ColorWiz

The clearest difference is in-app purchases: ColorWiz at none against EE ToolKit's 1. EE ToolKit's advantage is ratings volume (1.4K vs 6) and rating (4.7 vs 4.3). On price, ads and device support there is nothing between them.

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

EE ToolKit holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 6, so its average is the more settled of the two.

EE ToolKit ships an update every 3 months, ColorWiz every 10 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
