# The IRR App vs Compound Interest Calc

The IRR App 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 2, so its average is the more settled of the two.

The IRR App ships an update every 19 months, Compound Interest Calc every 3 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
