# PDF Voice Reader vs Biological Decoding

The clearest difference is rating: PDF Voice Reader at 4.1 against Biological Decoding's 3.0. PDF Voice Reader also leads on ratings volume (955 vs 6). Biological Decoding's advantage is ads (none vs shown) and iOS requirement (8.0 vs 26). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. PDF Voice Reader sells 16 in-app purchases, starting at $4.99 per month and Biological Decoding sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

PDF Voice Reader holds the better App Store score, 4.1 against 3.0. That said, the two scores are not equally well evidenced: PDF Voice Reader has 955 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 22% of PDF Voice Reader's written reviews are positive against 17% of Biological Decoding's.
