Rescue Machine! holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: Rescue Machine! has 109K ratings behind it against 27, so its average is the more settled of the two. Written reviews complicate that: 22% of Rescue Machine!'s written reviews are positive against 50% of Material Shifter's, so the app with the better star average is not the one people write more warmly about.
Rescue Machine! ships an update every 2 months, Material Shifter every 3 months. The most recent releases landed on September 25, 2026 and August 15, 2026 respectively.
