Use your iPhone Duo as a protractor. Fold it to match an angle and read the degrees. Requires iPhone Duo with iOS 27.1 or later. Measurement uses the phone's folding hinge and isn't available on other devices. MEASURE ON PAPER Stand the phone on its bottom edges and line up each edge with a line on the page. Open or close the fold until both edges match. CHECK TWO SURFACES Rest each half of the phone against a surface and fold it to fit the angle where they meet. Read the angle as you adjust it. KEEP YOUR READINGS Tap Record when you're ready. History groups your saved angles by day and shows the time of each reading. Delete individual readings or clear them all. Next time you need a protractor, unfold your phone.

Verdict
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.
