Verdict
The clearest difference is update cadence: Phenyx at daily against ReadGenius's every 2 weeks. Phenyx also leads on iOS requirement (13.0 vs 17.6). ReadGenius's advantage is ratings volume (5 vs 1). On price, rating, ads and in-app purchases 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. ReadGenius sells 2 in-app purchases, starting at $2.99 per month and Phenyx sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for ReadGenius against 5.0 for Phenyx. That said, the two scores are not equally well evidenced: ReadGenius has 5 ratings behind it against 1, so its average is the more settled of the two.
ReadGenius ships an update every 2 weeks, Phenyx daily. The most recent releases landed on October 30, 2026 and November 5, 2026 respectively.
