Verdict
The clearest difference is rating: Common Reader at 5.0 against Koodo Reader's 4.3. Common Reader also leads on in-app purchases (none vs 2) and update cadence (every 2 days vs monthly). Koodo Reader's advantage is ratings volume (9 vs 1) and iOS requirement (15.5 vs 26.0). On price, review sentiment, ads 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. Koodo Reader sells 2 one-off in-app purchases. Common Reader asks for nothing beyond the download.
Common Reader holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Koodo Reader has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 82% of Koodo Reader's written reviews are positive against 75% of Common Reader's, so the app with the better star average is not the one people write more warmly about.
Koodo Reader ships an update monthly, Common Reader every 2 days. The most recent releases landed on October 20, 2026 and October 14, 2026 respectively.
