# National Grid vs U

The clearest difference is rating: National Grid at 4.8 against U's 1.8. National Grid also leads on ratings volume (15K vs 11) and review sentiment (25% vs 0%). U's advantage is update cadence (every 3 weeks vs every 6 weeks). 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.

That said, the two scores are not equally well evidenced: National Grid has 15K ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 25% of National Grid's written reviews are positive against 0% of U's.

National Grid ships an update every 6 weeks, U every 3 weeks. The most recent releases landed on November 9, 2026 and November 3, 2026 respectively.
