Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Sutra ships an update weekly, iRead every 3 days. Both last shipped on October 25, 2026.
