Verdict
The clearest difference is ads: Cocam at none against GRImageViewer's shown. Cocam also leads on rating (3.9 vs 3.4) and update cadence (every 8 days vs every 3 weeks). GRImageViewer's advantage is ratings volume (42 vs 7). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. GRImageViewer sells 1 one-off in-app purchase and Cocam sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Cocam holds the better App Store score, 3.9 against 3.4. That said, the two scores are not equally well evidenced: GRImageViewer has 42 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 52% of GRImageViewer's written reviews are positive against 61% of Cocam's.
GRImageViewer ships an update every 3 weeks, Cocam every 8 days. The most recent releases landed on September 29, 2026 and October 7, 2026 respectively.
