# Breadpad vs Carapace

The clearest difference is review sentiment: Carapace at 100% against Breadpad's 33%. Carapace also leads on rating (5.0 vs 3.9) and in-app purchases (none vs 3). Breadpad's advantage is ratings volume (166 vs 1) and device support (4 vs 2). On price and ads there is nothing between them.

Both are free to download. Breadpad sells 3 in-app purchases, starting at $4.99 per month. Carapace asks for nothing beyond the download.

Carapace holds the better App Store score, 5.0 against 3.9.
