# SERIES vs 밀리의서재

SERIES and 밀리의서재 both sit at 4.5 stars, but that hides the real split: 69% of 밀리의서재's written reviews are positive against 30% of SERIES's. 밀리의서재 also leads on ads (none vs shown) and device support (4 vs 2). On price, rating, ratings volume and update cadence there is nothing between them.

Both are free to download. SERIES sells 10 one-off in-app purchases and 밀리의서재 sells 2 in-app purchases, starting at $10.99 per month. Whichever you choose, the download price is not the number that matters.
