# Kase₄ CE vs Collections Database

The clearest difference is rating: Kase₄ CE at 5.0 against Collections Database's 4.6. Collections Database's advantage is update cadence (fortnightly vs every 2 months) and ratings volume (190 vs 6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Kase₄ CE sells 7 in-app purchases, starting at $0.49 per month and Collections Database sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Kase₄ CE holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Collections Database has 190 ratings behind it against 6, so its average is the more settled of the two.

Kase₄ CE ships an update every 2 months, Collections Database fortnightly. The most recent releases landed on October 9, 2026 and October 16, 2026 respectively.
