Verdict
The clearest difference is rating: Hydrawise at 4.7 against U's 3.0. Hydrawise also leads on ratings volume (64K vs 1) and update cadence (every 3 weeks vs every 2 months). U's advantage is review sentiment (50% vs 38%) and iOS requirement (10.0 vs 15.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Hydrawise holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Hydrawise has 64K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of U's written reviews are positive against 38% of Hydrawise's, so the app with the better star average is not the one people write more warmly about.
U ships an update every 2 months, Hydrawise every 3 weeks. The most recent releases landed on June 1, 2026 and September 26, 2026 respectively.
