ReceptionRating · Positive reviews · Number of ratings

SNAIL ESC 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: 21% of ISD Link's written reviews are positive against 0% of SNAIL ESC's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ISD Link ships an update every 3 weeks, SNAIL ESC every 3 months. The most recent releases landed on October 12, 2026 and October 4, 2026 respectively.
