# 模拟来电 vs Cerulean

The clearest difference is in-app purchases: Cerulean at none against 模拟来电's 1. Cerulean also leads on update cadence (every 2 months vs every 6 months) and ratings volume (393 vs 56). 模拟来电's advantage is iOS requirement (9.0 vs 15.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. 模拟来电 sells 1 one-off in-app purchase. Cerulean asks for nothing beyond the download.

模拟来电 holds the better App Store score, 4.9 against 4.8. That said, the two scores are not equally well evidenced: Cerulean has 393 ratings behind it against 56, so its average is the more settled of the two. Written reviews point the same way: 91% of 模拟来电's written reviews are positive against 85% of Cerulean's.
