Verdict

The call

The clearest difference is rating: CrossMark at 5.0 against Stud Finder®'s 4.4. CrossMark also leads on monetization model (free vs free with in-app purchases). Stud Finder®'s advantage is ratings volume (23K vs 8). On price, review sentiment, update cadence and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

CrossMark holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Stud Finder® has 23K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 8% of Stud Finder®'s written reviews are positive against 0% of CrossMark's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Stud Finder® ships an update every 6 weeks, CrossMark every 2 months. The most recent releases landed on October 19, 2026 and October 8, 2026 respectively.
