Verdict
The clearest difference is rating: Readingo at 4.8 against CHM+'s 3.0. Readingo also leads on ads (none vs shown) and update cadence (weekly vs every 6 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Readingo sells 1 one-off in-app purchase and CHM+ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Readingo holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Readingo has 117 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 93% of Readingo's written reviews are positive against 83% of CHM+'s.
Readingo ships an update weekly, CHM+ every 6 weeks. The most recent releases landed on October 19, 2026 and October 12, 2026 respectively.
