# ePub Pro vs Instant Reader

The clearest difference is update cadence: Instant Reader at every 2 weeks against ePub Pro's every 3 months. Instant Reader also leads on iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. ePub Pro sells 1 one-off in-app purchase and Instant Reader sells 1 in-app purchase, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

ePub Pro ships an update every 3 months, Instant Reader every 2 weeks. The most recent releases landed on October 4, 2026 and September 26, 2026 respectively.
