Verdict
The clearest difference is rating: iRead at 5.0 against Readest's 4.5. iRead also leads on update cadence (every 3 days vs fortnightly). Readest's advantage is ratings volume (191 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Readest sells 9 in-app purchases, starting at $4.99 per month 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 4.5. That said, the two scores are not equally well evidenced: Readest has 191 ratings behind it against 1, so its average is the more settled of the two.
Readest ships an update fortnightly, iRead every 3 days. The most recent releases landed on October 20, 2026 and October 13, 2026 respectively.
