# EE ToolKit vs BLExAR

The clearest difference is price: EE ToolKit at Free against BLExAR's $4.99. EE ToolKit also leads on rating (4.7 vs 4.0) and ratings volume (1.4K vs 14). BLExAR's advantage is in-app purchases (none vs 1). On update cadence, ads and device support there is nothing between them.

EE ToolKit is free to download; BLExAR costs $4.99 up front. EE ToolKit sells 1 one-off in-app purchase. BLExAR asks for nothing beyond the download.

EE ToolKit holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 14, 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 75% of BLExAR's.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on October 12, 2026 and October 13, 2026 respectively.
