# Sky vs CGreen

The clearest difference is ads: Sky at none against CGreen's shown. Sky also leads on monetization model (free vs ad-supported) and iOS requirement (11.0 vs 13.0). CGreen's advantage is update cadence (every 2 days vs every 20 months) and rating (4.4 vs 4.0). On price, in-app purchases and device support there is nothing between them.

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

CGreen holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: CGreen has 8 ratings behind it against 1, so its average is the more settled of the two.

Sky ships an update every 20 months, CGreen every 2 days. The most recent releases landed on October 7, 2026 and October 3, 2026 respectively.
