Verdict
The clearest difference is review sentiment: Paper2Audio at 97% against NaturalReader's 71%. Paper2Audio also leads on monetization model (free vs free with in-app purchases) and rating (4.9 vs 4.6). NaturalReader's advantage is ratings volume (9.2K vs 784) and chart position (#147 vs unranked). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. NaturalReader sells 6 in-app purchases, starting at $9.99 per month and Paper2Audio sells 2 in-app purchases, starting at $20.00 per month. Whichever you choose, the download price is not the number that matters.
Paper2Audio holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: NaturalReader has 9.2K ratings behind it against 784, so its average is the more settled of the two. Written reviews point the same way: 71% of NaturalReader's written reviews are positive against 97% of Paper2Audio's.
NaturalReader ships an update every 3 weeks, Paper2Audio every 5 days. The most recent releases landed on November 10, 2026 and November 8, 2026 respectively.
