# Compound Gain vs Interest Calculator

The clearest difference is rating: Interest Calculator at 4.8 against Compound Gain's 4.4. Interest Calculator also leads on update cadence (every 2 weeks vs every 2 months) and ratings volume (117 vs 14). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Compound Gain sells 2 in-app purchases, starting at $1.39 per month and Interest Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Interest Calculator holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Interest Calculator has 117 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 80% of Compound Gain's written reviews are positive against 78% of Interest Calculator's, so the app with the better star average is not the one people write more warmly about.

Compound Gain ships an update every 2 months, Interest Calculator every 2 weeks. Both last shipped on October 24, 2026.
