In each mode, you can switch to camera view and take measurements of all objects around you. Additional Premium mode: Polygon measurement lets you draw any shape on your screen to check all its angles. Turn on the camera to see the real object through your phone and copy its shape. You can also pick a photo from your gallery or take a new picture to draw a shape on the image. In Premium mode, you can change colors, add helper lines, and switch between different angle units. All modes allows you to make a screenshot of anything on the screen. Enjoy !!!

Verdict

The call

Protractor Smart also leads on ads (none vs shown) and ratings volume (242 vs 2). iPinPoint's advantage is rating (5.0 vs 4.6) and iOS requirement (12.0 vs 14.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

iPinPoint holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Protractor Smart has 242 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of iPinPoint's written reviews are positive against 44% of Protractor Smart's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iPinPoint ships an update every 11 months, Protractor Smart every 21 months. The most recent releases landed on September 25, 2026 and October 13, 2026 respectively.
