Verdict
The clearest difference is review sentiment: Protractor Edge at 70% against iPinPoint's 0%. Protractor Edge also leads on ratings volume (55 vs 2) and iOS requirement (9.0 vs 12.0). iPinPoint's advantage is rating (5.0 vs 4.5) and update cadence (every 11 months vs every 43 months). On price, ads, 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 Edge sells 2 in-app purchases, starting at $1.99 per year. Whichever you choose, the download price is not the number that matters.
iPinPoint holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Protractor Edge has 55 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 70% of Protractor Edge'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 Edge every 43 months. The most recent releases landed on September 25, 2026 and October 16, 2026 respectively.
