# Refraktions vs Coil

The clearest difference is rating: Coil at 5.0 against Refraktions's 4.5. Coil also leads on update cadence (every 3 days vs every 2 months) and price ($0.99 vs $5.99). Refraktions's advantage is ratings volume (28 vs 1). On ads, in-app purchases, monetization model and device support there is nothing between them.

Refraktions costs $5.99 and Coil $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Coil holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Refraktions has 28 ratings behind it against 1, so its average is the more settled of the two.

Refraktions ships an update every 2 months, Coil every 3 days. The most recent releases landed on October 10, 2026 and October 13, 2026 respectively.
