# Anomaly vs Adopt a Book

The clearest difference is in-app purchases: Adopt a Book at none against Anomaly's 1. Adopt a Book also leads on update cadence (every 2 weeks vs every 35 months). Anomaly's advantage is ads (none vs shown) and iOS requirement (11.0 vs 15.5). On price and device support there is nothing between them.

Both are free to download. Anomaly sells 1 one-off in-app purchase. Adopt a Book asks for nothing beyond the download.

Anomaly ships an update every 35 months, Adopt a Book every 2 weeks. The most recent releases landed on October 8, 2026 and September 25, 2026 respectively.
