# SERIES vs Dooru Library

SERIES and Dooru Library both sit at 4.5 stars, but that hides the real split: 73% of Dooru Library's written reviews are positive against 30% of SERIES's. Dooru Library also leads on in-app purchases (none vs 15) and ads (none vs shown). SERIES's advantage is update cadence (every 3 weeks vs every 5 months) and ratings volume (2K vs 30). On price, rating and device support there is nothing between them.

Both are free to download. SERIES sells 14 one-off in-app purchases. Dooru Library asks for nothing beyond the download.

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 30, so its average is the more settled of the two. Written reviews complicate that: 30% of SERIES's written reviews are positive against 73% of Dooru Library's, so the app with the better star average is not the one people write more warmly about.

SERIES ships an update every 3 weeks, Dooru Library every 5 months. Both last shipped on October 20, 2026.
