Verdict

The call

The clearest difference is review sentiment: CMC Field Guide at 78% against Bryx Mobile's 49%. CMC Field Guide also leads on iOS requirement (15.1 vs 18.2). Bryx Mobile's advantage is update cadence (fortnightly vs every 3 months) and rating (4.2 vs 4.0). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Bryx Mobile holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Bryx Mobile has 282 ratings behind it against 24, so its average is the more settled of the two. Written reviews complicate that: 78% of CMC Field Guide's written reviews are positive against 49% of Bryx Mobile's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CMC Field Guide ships an update every 3 months, Bryx Mobile fortnightly. Both last shipped on October 16, 2026.
