Verdict
The clearest difference is rating: USmart Go at 2.7 against LIFAair's 2.0. USmart Go also leads on update cadence (every 5 days vs every 3 weeks) and ratings volume (59 vs 4). LIFAair's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
USmart Go holds the better App Store score, 2.7 against 2.0. That said, the two scores are not equally well evidenced: USmart Go has 59 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 5% of LIFAair's written reviews are positive against 0% of USmart Go's, so the app with the better star average is not the one people write more warmly about.
LIFAair ships an update every 3 weeks, USmart Go every 5 days. Both last shipped on October 24, 2026.
