# Refraktions vs Jamulator

The clearest difference is price: Jamulator at Free against Refraktions's $5.99. Jamulator also leads on update cadence (weekly vs every 2 months) and review sentiment (100% vs 90%). Refraktions's advantage is rating (4.5 vs 3.8) and in-app purchases (none vs 1). On ads and device support there is nothing between them.

Jamulator is free to download; Refraktions costs $5.99 up front. Jamulator sells 1 one-off in-app purchase. Refraktions asks for nothing beyond the download.

Refraktions holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: Refraktions has 28 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 90% of Refraktions's written reviews are positive against 100% of Jamulator's, so the app with the better star average is not the one people write more warmly about.

Refraktions ships an update every 2 months, Jamulator weekly. The most recent releases landed on September 24, 2026 and October 5, 2026 respectively.
