# KnowledgeCity vs ethrai

The clearest difference is review sentiment: KnowledgeCity at 100% against ethrai's 40%. KnowledgeCity also leads on in-app purchases (none vs 22) and rating (4.7 vs 4.3). ethrai's advantage is ratings volume (285 vs 40) and device support (3 vs 1). On price, update cadence and ads there is nothing between them.

Both are free to download. ethrai sells 18 one-off in-app purchases. KnowledgeCity asks for nothing beyond the download.

KnowledgeCity holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: ethrai has 285 ratings behind it against 40, so its average is the more settled of the two.
