# GameSir vs KeyLinker

The clearest difference is review sentiment: KeyLinker at 30% against GameSir's 11%. KeyLinker also leads on iOS requirement (13.0 vs 15.0). GameSir's advantage is update cadence (every 3 weeks vs every 2 months) and ratings volume (1.2K vs 52). On price, ads, in-app purchases and monetization model there is nothing between them.

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

GameSir holds the better App Store score, 2.5 against 2.3. That said, the two scores are not equally well evidenced: GameSir has 1.2K ratings behind it against 52, so its average is the more settled of the two. Written reviews complicate that: 11% of GameSir'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.

GameSir ships an update every 3 weeks, KeyLinker every 2 months. The most recent releases landed on October 14, 2026 and October 16, 2026 respectively.
