# bREADER vs iBunkoS

The clearest difference is review sentiment: bREADER at 95% against iBunkoS's 58%. bREADER also leads on update cadence (every 3 weeks vs every 2 months) and iOS requirement (10.1 vs 12.0). iBunkoS's advantage is rating (4.4 vs 4.0) and chart position (#52 vs unranked). On ads, in-app purchases, monetization model and device support there is nothing between them.

bREADER costs $3.99 and iBunkoS $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

iBunkoS holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: iBunkoS has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 95% of bREADER's written reviews are positive against 58% of iBunkoS's, so the app with the better star average is not the one people write more warmly about.

bREADER ships an update every 3 weeks, iBunkoS every 2 months. The most recent releases landed on September 21, 2026 and September 27, 2026 respectively.
