Verdict
The clearest difference is rating: RuiDeng at 3.0 against ISD Link's 2.1. ISD Link's advantage is update cadence (every 3 weeks vs every 3 months) and review sentiment (21% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
RuiDeng holds the better App Store score, 3.0 against 2.1. That said, the two scores are not equally well evidenced: ISD Link has 23 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of RuiDeng's written reviews are positive against 21% of ISD Link's, so the app with the better star average is not the one people write more warmly about.
RuiDeng ships an update every 3 months, ISD Link every 3 weeks. The most recent releases landed on September 21, 2026 and September 25, 2026 respectively.
