# my books library vs Protanopia

The clearest difference is in-app purchases: Protanopia at none against my books library's 3. Protanopia also leads on rating (4.8 vs 4.3) and review sentiment (97% vs 71%). my books library's advantage is update cadence (every 5 days vs every 5 months). On price, ads and device support there is nothing between them.

Both are free to download. my books library sells 3 in-app purchases, starting at $1.99 per month. Protanopia asks for nothing beyond the download.

Protanopia holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Protanopia has 323 ratings behind it against 21, so its average is the more settled of the two. Written reviews point the same way: 71% of my books library's written reviews are positive against 97% of Protanopia's.

my books library ships an update every 5 days, Protanopia every 5 months. Both last shipped on October 24, 2026.
