# Refrigeration.AI vs Sunset Technology

The clearest difference is rating: Sunset Technology at 5.0 against Refrigeration.AI's 4.5. Sunset Technology also leads on review sentiment (100% vs 75%). Refrigeration.AI's advantage is in-app purchases (none vs 1) and ratings volume (20 vs 3). On price, ads and device support there is nothing between them.

Both are free to download. Sunset Technology sells 1 in-app purchase, starting at $4.99 per month. Refrigeration.AI asks for nothing beyond the download.

Sunset Technology holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Refrigeration.AI has 20 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 75% of Refrigeration.AI's written reviews are positive against 100% of Sunset Technology's.
