# iPinPoint vs Protractor Smart

The clearest difference is review sentiment: Protractor Smart at 44% against iPinPoint's 0%. 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.

Both are free to download. iPinPoint sells 6 one-off in-app purchases and Protractor Smart sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

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.

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.
