# forecast.co.uk vs Rainbow AI

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.

Both are free to download. Rainbow AI sells 10 in-app purchases, starting at $3.99 per 7 days. forecast.co.uk asks for nothing beyond the download.

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.

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.
