# Nutstore vs ivySCI

The clearest difference is ratings volume: Nutstore at 431 against ivySCI's 9. Nutstore also leads on review sentiment (89% vs 80%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Nutstore sells 2 in-app purchases, starting at $34.99 per year and ivySCI sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
