Double Number Merging holds the better App Store score, 3.9 against 2.3. That said, the two scores are not equally well evidenced: Double Number Merging has 779 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 8% of Sky Plunger's written reviews are positive against 7% of Double Number Merging's, so the app with the better star average is not the one people write more warmly about.
Sky Plunger ships an update every 18 months, Double Number Merging every 3 months. The most recent releases landed on October 24, 2026 and October 30, 2026 respectively.
