Verdict

The call

The clearest difference is in-app purchases: forecast.co.uk at none against Rainbow AI's 10. forecast.co.uk also leads on review sentiment (51% vs 39%) and device support (3 vs 1). Rainbow AI's advantage is rating (4.5 vs 4.0) and ratings volume (725 vs 2). On price, ads and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Rainbow AI holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Rainbow AI has 725 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 51% of forecast.co.uk's written reviews are positive against 39% of Rainbow AI's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

forecast.co.uk ships an update every 4 weeks, Rainbow AI every 11 days. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
