Verdict

The call

The clearest difference is price: Cocam at Free against GR Linker's $7.99. Cocam also leads on update cadence (every 8 days vs every 2 months) and iOS requirement (12.0 vs 15.0). GR Linker's advantage is rating (4.5 vs 3.9) and in-app purchases (none vs 3). On review sentiment, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

GR Linker holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: GR Linker has 114 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 58% of GR Linker's written reviews are positive against 61% of Cocam's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

GR Linker ships an update every 2 months, Cocam every 8 days. The most recent releases landed on October 14, 2026 and October 7, 2026 respectively.
