# CD Calculator vs Interest Rate Calculation

The clearest difference is in-app purchases: Interest Rate Calculation at none against CD Calculator's 1. Interest Rate Calculation also leads on update cadence (every 6 days vs every 32 months). CD Calculator's advantage is ratings volume (265 vs 6) and iOS requirement (14.0 vs 16.6). On price, rating, ads and device support there is nothing between them.

Both are free to download. CD Calculator sells 1 one-off in-app purchase. Interest Rate Calculation asks for nothing beyond the download.

Interest Rate Calculation holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: CD Calculator has 265 ratings behind it against 6, so its average is the more settled of the two.

CD Calculator ships an update every 32 months, Interest Rate Calculation every 6 days. Both last shipped on November 3, 2026.
