Verdict

The call

The clearest difference is rating: GR Lab at 4.1 against GRImageViewer's 3.3. GR Lab also leads on ads (none vs shown) and update cadence (every 9 days vs every 3 weeks). GRImageViewer's advantage is iOS requirement (14.0 vs 17.0). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.

Both are free to download. GRImageViewer sells 1 one-off in-app purchase and GR Lab sells 6 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

GR Lab holds the better App Store score, 4.1 against 3.3. Both are backed by a comparable volume of ratings — 44 and 24 respectively. Written reviews complicate that: 52% of GRImageViewer's written reviews are positive against 50% of GR Lab's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

GRImageViewer ships an update every 3 weeks, GR Lab every 9 days. The most recent releases landed on November 3, 2026 and November 8, 2026 respectively.
