# Crestools vs Protractor°

The clearest difference is rating: Protractor° at 5.0 against Crestools's 4.2. Protractor° also leads on update cadence (every 2 days vs every 4 months) and monetization model (free vs free with in-app purchases). Crestools's advantage is ratings volume (31 vs 1) and device support (3 vs 1). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Crestools sells 3 in-app purchases, starting at $19.99 per year and Protractor° sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Protractor° holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Crestools has 31 ratings behind it against 1, so its average is the more settled of the two.

Crestools ships an update every 4 months, Protractor° every 2 days. The most recent releases landed on November 2, 2026 and October 31, 2026 respectively.
