# U vs SmartAI

The clearest difference is rating: SmartAI at 4.6 against U's 3.0. SmartAI also leads on ratings volume (71 vs 2). U's advantage is update cadence (every 3 months vs every 20 months). On price, review sentiment, 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.

SmartAI holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: SmartAI has 71 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 14% of U's written reviews are positive against 17% of SmartAI's.

U ships an update every 3 months, SmartAI every 20 months. The most recent releases landed on October 7, 2026 and October 25, 2026 respectively.
