# Koppa vs FlashFluency

The clearest difference is ratings volume: Koppa at 354 against FlashFluency's 3. Koppa also leads on update cadence (every 4 days vs every 3 weeks). FlashFluency's advantage is review sentiment (100% vs 87%) and iOS requirement (13.0 vs 15.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Koppa sells 8 in-app purchases, starting at $2.99 per 7 days and FlashFluency sells 2 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Koppa against 5.0 for FlashFluency. That said, the two scores are not equally well evidenced: Koppa has 354 ratings behind it against 3, so its average is the more settled of the two.
