# Stud Finder® vs CrossMark

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.

Both are free to download. Stud Finder® sells 2 in-app purchases, starting at $1.99 per 7 days and CrossMark sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

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.

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.
