# G2 Performance vs CosKit

The clearest difference is rating: CosKit at 5.0 against G2 Performance's 3.9. CosKit also leads on update cadence (every 8 days vs every 3 weeks). G2 Performance's advantage is in-app purchases (none vs 1) and ratings volume (7 vs 1). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. CosKit sells 1 one-off in-app purchase. G2 Performance asks for nothing beyond the download.

CosKit holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: G2 Performance has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

G2 Performance ships an update every 3 weeks, CosKit every 8 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
