# Studyflash vs Retain Cards

The clearest difference is rating: Retain Cards at 5.0 against Studyflash's 4.1. Studyflash's advantage is ratings volume (69 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Studyflash sells 5 in-app purchases, starting at $14.99 per month and Retain Cards sells 3 in-app purchases, starting at $1.59 per 7 days. Whichever you choose, the download price is not the number that matters.
