# SERIES vs 교보eBook

The clearest difference is ads: 교보eBook at none against SERIES's shown. SERIES's advantage is rating (4.5 vs 4.3) and chart position (#49 vs unranked). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. SERIES sells 14 one-off in-app purchases and 교보eBook sells 6 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

SERIES holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: SERIES has 2K ratings behind it against 290, so its average is the more settled of the two. Written reviews point the same way: 30% of SERIES's written reviews are positive against 21% of 교보eBook's.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
