Verdict
The clearest difference is review sentiment: Protractor at 64% against Protractor+'s 15%. Protractor+'s advantage is rating (4.1 vs 1.8) and ratings volume (10K vs 6). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Protractor+ sells 1 one-off in-app purchase and Protractor sells 6 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Protractor+ holds the better App Store score, 4.1 against 1.8. That said, the two scores are not equally well evidenced: Protractor+ has 10K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 15% of Protractor+'s written reviews are positive against 64% of Protractor's, so the app with the better star average is not the one people write more warmly about.
Protractor+ ships an update every 2 months, Protractor every 5 weeks. The most recent releases landed on October 15, 2026 and October 2, 2026 respectively.
