# memoryOS vs ReaderPro

The clearest difference is review sentiment: memoryOS at 80% against ReaderPro's 0%. memoryOS also leads on rating (4.9 vs 1.0) and ratings volume (16K vs 1). ReaderPro's advantage is update cadence (every 4 days vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. memoryOS sells 20 in-app purchases, starting at $3.99 per 7 days and ReaderPro sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

memoryOS holds the better App Store score, 4.9 against 1.0. That said, the two scores are not equally well evidenced: memoryOS has 16K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 80% of memoryOS's written reviews are positive against 0% of ReaderPro's.

memoryOS ships an update every 3 weeks, ReaderPro every 4 days. The most recent releases landed on October 2, 2026 and September 23, 2026 respectively.
