Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
SNAIL ESC holds the better App Store score, 3.0 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: 19% of ISD Go'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.
ISD Go ships an update weekly, SNAIL ESC every 3 months. The most recent releases landed on July 8, 2026 and July 6, 2026 respectively.
