Razer PS Controller holds the better App Store score, 4.7 against 2.3. That said, the two scores are not equally well evidenced: Razer PS Controller has 946 ratings behind it against 49, so its average is the more settled of the two. Written reviews complicate that: 11% of Razer PS Controller's written reviews are positive against 30% of KeyLinker's, so the app with the better star average is not the one people write more warmly about.
Razer PS Controller ships an update every 3 months, KeyLinker every 2 months. The most recent releases landed on October 13, 2026 and October 7, 2026 respectively.
