Verdict
The clearest difference is rating: BionRead at 5.0 against Celer's 4.0. BionRead also leads on monetization model (free vs freemium). Celer's advantage is update cadence (every 10 days vs every 7 months) and ratings volume (21 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Celer sells 4 in-app purchases, starting at $7.99 per month and BionRead sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
BionRead holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Celer has 21 ratings behind it against 1, so its average is the more settled of the two.
Celer ships an update every 10 days, BionRead every 7 months. The most recent releases landed on September 21, 2026 and July 31, 2026 respectively.
