Verdict

The call

The clearest difference is monetization model: Readify AI at free against Common Reader's free with in-app purchases. Readify AI also leads on ratings volume (105 vs 1) and review sentiment (90% vs 75%). Common Reader's advantage is update cadence (every 2 days vs weekly) and rating (5.0 vs 4.8). On price, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Common Reader holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Readify AI has 105 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 75% of Common Reader's written reviews are positive against 90% of Readify AI's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Common Reader ships an update every 2 days, Readify AI weekly. The most recent releases landed on October 14, 2026 and October 22, 2026 respectively.
