# Thermals vs Breadpad

The clearest difference is review sentiment: Thermals at 83% against Breadpad's 33%. Thermals also leads on rating (4.5 vs 3.9) and in-app purchases (none vs 3). Breadpad's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (166 vs 28). On price, ads, device support and iOS requirement there is nothing between them.

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

Thermals holds the better App Store score, 4.5 against 3.9.
