ReceptionRating · Positive reviews · Number of ratings

Blue Days holds the better App Store score, 4.2 against 2.3. That said, the two scores are not equally well evidenced: Blue Days has 239 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 44% of Blue Days's written reviews are positive against 67% of WeatherRadar Basic's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Blue Days ships an update fortnightly, WeatherRadar Basic every 4 months. The most recent releases landed on October 4, 2026 and September 27, 2026 respectively.
