# Protractor+ vs Level Tool

The clearest difference is ads: Protractor+ at none against Level Tool's shown. Protractor+ also leads on ratings volume (10K vs 35). Level Tool's advantage is review sentiment (36% vs 15%) and update cadence (monthly vs every 2 months). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Protractor+ sells 1 one-off in-app purchase and Level Tool sells 5 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Protractor+ holds the better App Store score, 4.1 against 3.9. That said, the two scores are not equally well evidenced: Protractor+ has 10K ratings behind it against 35, so its average is the more settled of the two. Written reviews complicate that: 15% of Protractor+'s written reviews are positive against 36% of Level Tool'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, Level Tool monthly. The most recent releases landed on November 1, 2026 and October 26, 2026 respectively.
