# Protractor+ vs Protractor Edge

Protractor+ and Protractor Edge both sit at 4.1 stars, but that hides the real split: 67% of Protractor Edge's written reviews are positive against 15% of Protractor+'s. Protractor Edge also leads on iOS requirement (13.0 vs 17.6). Protractor+'s advantage is ads (none vs shown) and ratings volume (10K vs 2). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Protractor+ sells 1 one-off in-app purchase and Protractor Edge sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.1 for Protractor+ against 4.0 for Protractor Edge. That said, the two scores are not equally well evidenced: Protractor+ has 10K ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 15% of Protractor+'s written reviews are positive against 67% of Protractor Edge's.

Protractor+ ships an update every 2 months, Protractor Edge every 6 weeks. The most recent releases landed on September 22, 2026 and September 20, 2026 respectively.
