# Razer PS Controller vs KeyLinker

The clearest difference is rating: Razer PS Controller at 4.7 against KeyLinker's 2.3. Razer PS Controller also leads on ratings volume (946 vs 49). KeyLinker's advantage is review sentiment (30% vs 11%) and iOS requirement (13.0 vs 15.4). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

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.
