# SimpleMoon vs 鲨鱼天气

SimpleMoon holds the better App Store score, 4.9 against 4.6. Both are backed by a comparable volume of ratings — 302 and 198 respectively. Written reviews complicate that: 86% of SimpleMoon's written reviews are positive against 92% of 鲨鱼天气's, so the app with the better star average is not the one people write more warmly about.
