# CO vs FancyView

The clearest difference is rating: CO at 4.5 against FancyView's 3.0. CO also leads on ratings volume (1.2K vs 7). FancyView's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, review sentiment, update cadence 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.

CO holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: CO has 1.2K ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 27% of CO's written reviews are positive against 25% of FancyView's.

CO ships an update fortnightly, FancyView every 11 days. The most recent releases landed on November 7, 2026 and October 30, 2026 respectively.
