# Yi iot⁺ vs sulink

The clearest difference is rating: Yi iot⁺ at 4.1 against sulink's 3.5. Yi iot⁺ also leads on ads (none vs shown) and ratings volume (477 vs 12). sulink's advantage is update cadence (fortnightly vs every 5 weeks). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Yi iot⁺ sells 8 in-app purchases, starting at $4.99 per 7 days and sulink sells 22 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Yi iot⁺ holds the better App Store score, 4.1 against 3.5. That said, the two scores are not equally well evidenced: Yi iot⁺ has 477 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 21% of Yi iot⁺'s written reviews are positive against 22% of sulink's, so the app with the better star average is not the one people write more warmly about.

Yi iot⁺ ships an update every 5 weeks, sulink fortnightly. Both last shipped on October 30, 2026.
