The clearest difference is rating: DuoCards at 4.7 against Master Reading Comprehension's 1.0. DuoCards also leads on ratings volume (1.3K vs 1). Master Reading Comprehension's advantage is ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. DuoCards sells 10 in-app purchases, starting at $19.99 per month and Master Reading Comprehension sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
