Verdict
The clearest difference is rating: S1Fun at 5.0 against ReadOn.'s 4.7. S1Fun also leads on iOS requirement (12.0 vs 17.0). ReadOn.'s advantage is ratings volume (13 vs 1). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. ReadOn. sells 4 in-app purchases, starting at $0.99 per 7 days and S1Fun sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
S1Fun holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: ReadOn. has 13 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
ReadOn. ships an update every 2 months, S1Fun monthly. The most recent releases landed on October 13, 2026 and October 4, 2026 respectively.
