Both are free to download. GRImageViewer sells 1 one-off in-app purchase. Phocus Mobile asks for nothing beyond the download.
Phocus Mobile holds the better App Store score, 4.6 against 3.4. That said, the two scores are not equally well evidenced: Phocus Mobile has 522 ratings behind it against 42, so its average is the more settled of the two. Written reviews complicate that: 47% of Phocus Mobile's written reviews are positive against 52% of GRImageViewer's, so the app with the better star average is not the one people write more warmly about.
Phocus Mobile ships an update every 2 weeks, GRImageViewer every 3 weeks. The most recent releases landed on September 26, 2026 and September 29, 2026 respectively.
