Verdict

The call

The clearest difference is review sentiment: BerlinCaseViewer at 91% against Zebdoc's 0%. BerlinCaseViewer also leads on ratings volume (18 vs 1) and iOS requirement (9.1 vs 15.1). Zebdoc's advantage is in-app purchases (none vs 16) and rating (5.0 vs 4.6). On price, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Zebdoc holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: BerlinCaseViewer has 18 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 91% of BerlinCaseViewer's written reviews are positive against 0% of Zebdoc's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

BerlinCaseViewer ships an update every 2 months, Zebdoc every 5 weeks. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
