# Paley Growth vs Multiplier

The clearest difference is rating: Multiplier at 4.6 against Paley Growth's 3.7. Multiplier also leads on ratings volume (24 vs 3). Paley Growth's advantage is monetization model (free vs paid) and review sentiment (100% vs 83%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Multiplier holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Multiplier has 24 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Paley Growth's written reviews are positive against 83% of Multiplier's, so the app with the better star average is not the one people write more warmly about.

Paley Growth ships an update every 3 months, Multiplier every 6 months. The most recent releases landed on October 6, 2026 and October 15, 2026 respectively.
