# YI Smart vs Yi iot +

The clearest difference is rating: Yi iot + at 4.1 against YI Smart's 1.8. Yi iot + also leads on monetization model (free with in-app purchases vs subscription) and ads (none vs shown). YI Smart's advantage is update cadence (every 10 days vs every 6 weeks) and iOS requirement (13.0 vs 17). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. YI Smart sells 20 in-app purchases, starting at $3.99 per month and Yi iot + sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Yi iot + holds the better App Store score, 4.1 against 1.8. That said, the two scores are not equally well evidenced: Yi iot + has 886 ratings behind it against 72, so its average is the more settled of the two.

YI Smart ships an update every 10 days, Yi iot + every 6 weeks. The most recent releases landed on September 16, 2026 and September 22, 2026 respectively.
