Verdict
The clearest difference is monetization model: Koodo Reader at free against Mythos Reader's freemium. Koodo Reader also leads on rating (4.5 vs 4.2). On price, review sentiment, ratings volume and update cadence 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 and Mythos Reader sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
Koodo Reader holds the better App Store score, 4.5 against 4.2. Both are backed by a comparable volume of ratings — 11 and 6 respectively. Written reviews complicate that: 82% of Koodo Reader's written reviews are positive against 86% of Mythos 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, Mythos Reader every 2 weeks. The most recent releases landed on October 30, 2026 and October 25, 2026 respectively.
