ReceptionRating · Positive reviews · Number of ratings

河川カメラ holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: YoWindow Weather has 1K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 85% of YoWindow Weather's written reviews are positive against 24% of 河川カメラ's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

YoWindow Weather ships an update monthly, 河川カメラ every 3 weeks. The most recent releases landed on November 10, 2026 and November 7, 2026 respectively.
