# StorAI vs eReader

The clearest difference is ads: StorAI at none against eReader's shown. StorAI also leads on update cadence (every 5 days vs every 3 months) and iOS requirement (17.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. StorAI sells 7 in-app purchases, starting at $6.99 per 7 days and eReader sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

StorAI ships an update every 5 days, eReader every 3 months. The most recent releases landed on November 4, 2026 and October 31, 2026 respectively.
