# DuoCards vs ESLFLIX

The clearest difference is rating: DuoCards at 4.7 against ESLFLIX's 4.0. DuoCards also leads on ratings volume (1.5K vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. DuoCards sells 9 in-app purchases, starting at $19.99 per month and ESLFLIX sells 1 in-app purchase, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

DuoCards holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: DuoCards has 1.5K ratings behind it against 1, so its average is the more settled of the two.
