# Protractor+ vs CAGR Calculator

The clearest difference is review sentiment: CAGR Calculator at 100% against Protractor+'s 15%. CAGR Calculator also leads on rating (4.7 vs 4.1) and iOS requirement (13.0 vs 17.6). Protractor+'s advantage is update cadence (every 2 months vs every 20 months) and ratings volume (10K vs 32). On price, ads, 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 CAGR Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CAGR Calculator holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: Protractor+ has 10K ratings behind it against 32, so its average is the more settled of the two. Written reviews point the same way: 15% of Protractor+'s written reviews are positive against 100% of CAGR Calculator's.

Protractor+ ships an update every 2 months, CAGR Calculator every 20 months. The most recent releases landed on October 11, 2026 and October 5, 2026 respectively.
