Verdict
The clearest difference is rating: Slope Calculator at 4.3 against Scale Ratio's 3.7. Slope Calculator also leads on ratings volume (105 vs 3). Scale Ratio's advantage is update cadence (fortnightly vs every 14 months) and review sentiment (83% vs 58%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Scale Ratio sells 1 one-off in-app purchase and Slope Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Slope Calculator holds the better App Store score, 4.3 against 3.7. That said, the two scores are not equally well evidenced: Slope Calculator has 105 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 83% of Scale Ratio's written reviews are positive against 58% of Slope Calculator's, so the app with the better star average is not the one people write more warmly about.
Scale Ratio ships an update fortnightly, Slope Calculator every 14 months. The most recent releases landed on November 2, 2026 and November 7, 2026 respectively.
