# Protractor+ vs Stud Finder

The clearest difference is update cadence: Stud Finder at every 11 days against Protractor+'s every 2 months. Stud Finder also leads on monetization model (free vs free with in-app purchases). Protractor+'s advantage is ratings volume (10K vs 7) and review sentiment (15% vs 0%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Protractor+ sells 1 one-off in-app purchase and Stud Finder sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: Protractor+ has 10K ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 15% of Protractor+'s written reviews are positive against 0% of Stud Finder's.

Protractor+ ships an update every 2 months, Stud Finder every 11 days. The most recent releases landed on September 25, 2026 and August 19, 2026 respectively.
