# Compounder vs Compound Interest Calc

The clearest difference is in-app purchases: Compounder at none against Compound Interest Calc's 1. Compounder also leads on ratings volume (4.3K vs 15) and rating (4.8 vs 4.6). Compound Interest Calc's advantage is iOS requirement (13.0 vs 16.0). On price, ads and device support there is nothing between them.

Both are free to download. Compound Interest Calc sells 1 one-off in-app purchase. Compounder asks for nothing beyond the download.

Compounder holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Compounder has 4.3K ratings behind it against 15, so its average is the more settled of the two. Written reviews point the same way: 61% of Compounder's written reviews are positive against 50% of Compound Interest Calc's.
