Verdict
The clearest difference is rating: Rain Bird at 4.7 against U's 3.0. Rain Bird also leads on ratings volume (70K vs 1). U's advantage is review sentiment (50% vs 31%) and iOS requirement (10.0 vs 13.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Rain Bird holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Rain Bird has 70K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 31% of Rain Bird's written reviews are positive against 50% of U's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 26, 2026 and June 1, 2026 respectively.
