Verdict
The clearest difference is rating: Audia at 5.0 against Readest's 4.5. Audia also leads on review sentiment (100% vs 84%) and update cadence (every 5 days vs fortnightly). Readest's advantage is ratings volume (201 vs 1) and chart position (#191 vs unranked). 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. Readest sells 9 in-app purchases, starting at $4.99 per month and Audia sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Audia holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Readest has 201 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 84% of Readest's written reviews are positive against 100% of Audia's.
Readest ships an update fortnightly, Audia every 5 days. The most recent releases landed on November 11, 2026 and November 10, 2026 respectively.
