Verdict
The clearest difference is rating: iRead at 5.0 against Sutra's 4.3. iRead also leads on update cadence (every 3 days vs weekly). Sutra's advantage is monetization model (free vs freemium) and ratings volume (17 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Sutra sells 4 one-off in-app purchases and iRead sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
iRead holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Sutra has 17 ratings behind it against 1, so its average is the more settled of the two.
Sutra ships an update weekly, iRead every 3 days. Both last shipped on October 25, 2026.
