# CZone vs BILGE

The clearest difference is rating: CZone at 5.0 against BILGE's 4.3. CZone also leads on iOS requirement (8.0 vs 16.6). BILGE's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (8 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

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

CZone holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: BILGE has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

CZone ships an update every 3 months, BILGE fortnightly. The most recent releases landed on October 18, 2026 and October 24, 2026 respectively.
