Verdict
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.
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. Neither carries in-app purchases, so what you see is what you pay.
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.
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.
