# Preen Display vs Stud Finder App

The clearest difference is rating: Preen Display at 5.0 against Stud Finder App's 4.4. Preen Display also leads on ads (none vs shown) and update cadence (weekly vs every 2 months). Stud Finder App's advantage is ratings volume (5 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Preen Display sells 2 in-app purchases, starting at $2.99 per month and Stud Finder App sells 2 in-app purchases, starting at $9.99 per year. Whichever you choose, the download price is not the number that matters.
