Verdict
The clearest difference is review sentiment: SuperX at 100% against Reader's 57%. SuperX also leads on ratings volume (19 vs 3). Reader's advantage is rating (5.0 vs 4.0) and update cadence (weekly vs every 8 months). On price, ads, in-app purchases and monetization model 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. Reader sells 1 one-off in-app purchase and SuperX sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Reader holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: SuperX has 19 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 57% of Reader's written reviews are positive against 100% of SuperX's, so the app with the better star average is not the one people write more warmly about.
Reader ships an update weekly, SuperX every 8 months. The most recent releases landed on October 10, 2026 and October 14, 2026 respectively.
