Verdict

The call

The clearest difference is in-app purchases: VS_UFO at none against Yi iot's 10. VS_UFO also leads on ads (none vs shown) and review sentiment (40% vs 5%). Yi iot's advantage is ratings volume (5K vs 32). On price, rating, update cadence and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Yi iot holds the better App Store score, 3.1 against 2.9. That said, the two scores are not equally well evidenced: Yi iot has 5K ratings behind it against 32, so its average is the more settled of the two. Written reviews complicate that: 40% of VS_UFO's written reviews are positive against 5% of Yi iot's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

VS_UFO ships an update fortnightly, Yi iot every 2 weeks. The most recent releases landed on November 2, 2026 and November 11, 2026 respectively.
