Verdict

The call

The clearest difference is rating: Koodo Reader at 4.4 against Common Reader's 3.0. Koodo Reader also leads on monetization model (free vs free with in-app purchases) and ratings volume (13 vs 2). Common Reader's advantage is update cadence (every 3 days vs monthly). On price, review sentiment, ads and in-app purchases there is nothing between them.
