# Compound Interest Calc vs Prosper

The clearest difference is ads: Prosper at none against Compound Interest Calc's shown. Prosper also leads on review sentiment (100% vs 69%) and update cadence (every 3 weeks vs every 3 months). Compound Interest Calc's advantage is ratings volume (6.7K vs 1). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Compound Interest Calc sells 1 one-off in-app purchase and Prosper sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Prosper holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Compound Interest Calc has 6.7K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 69% of Compound Interest Calc's written reviews are positive against 100% of Prosper's.

Compound Interest Calc ships an update every 3 months, Prosper every 3 weeks. The most recent releases landed on October 29, 2026 and October 10, 2026 respectively.
