# MorseCAT vs LemurKey

The clearest difference is rating: LemurKey at 5.0 against MorseCAT's 4.0. LemurKey also leads on in-app purchases (none vs 1) and ratings volume (6 vs 1). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. MorseCAT sells 1 one-off in-app purchase. LemurKey asks for nothing beyond the download.

LemurKey holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: LemurKey has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
