# HiReader vs CHM+

The clearest difference is rating: HiReader at 4.4 against CHM+'s 3.0. HiReader also leads on ads (none vs shown) and update cadence (every 9 days vs every 6 weeks). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. HiReader sells 3 in-app purchases, starting at $1.99 per month and CHM+ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

HiReader holds the better App Store score, 4.4 against 3.0. That said, the two scores are not equally well evidenced: HiReader has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 88% of HiReader's written reviews are positive against 83% of CHM+'s.

HiReader ships an update every 9 days, CHM+ every 6 weeks. The most recent releases landed on September 22, 2026 and September 26, 2026 respectively.
