Verdict

The call

The clearest difference is rating: ChargerLink at 4.0 against ISD Go's 1.8. ChargerLink also leads on iOS requirement (8.0 vs 11.0). ISD Go's advantage is update cadence (weekly vs every 2 months) and ratings volume (30 vs 2). On price, review sentiment, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

ChargerLink holds the better App Store score, 4.0 against 1.8. That said, the two scores are not equally well evidenced: ISD Go has 30 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 11% of ChargerLink's written reviews are positive against 19% of ISD Go's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ChargerLink ships an update every 2 months, ISD Go weekly. The most recent releases landed on October 13, 2026 and October 20, 2026 respectively.
