Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Readest ships an update fortnightly, Audia every 5 days. The most recent releases landed on November 11, 2026 and November 10, 2026 respectively.
