# STELLA Libraries vs Slomin's Shield

The clearest difference is rating: Slomin's Shield at 4.8 against STELLA Libraries's 3.7. Slomin's Shield also leads on ratings volume (3.8K vs 22) and update cadence (every 3 weeks vs every 4 months). STELLA Libraries's advantage is review sentiment (60% vs 40%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Slomin's Shield holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: Slomin's Shield has 3.8K ratings behind it against 22, so its average is the more settled of the two. Written reviews complicate that: 60% of STELLA Libraries's written reviews are positive against 40% of Slomin's Shield's, so the app with the better star average is not the one people write more warmly about.

STELLA Libraries ships an update every 4 months, Slomin's Shield every 3 weeks. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
