# Catalyst Edit vs REACTOR

The clearest difference is rating: Catalyst Edit at 4.7 against REACTOR's 3.4. Catalyst Edit also leads on ratings volume (254 vs 23) and device support (3 vs 1). REACTOR's advantage is review sentiment (47% vs 27%). On price, update cadence, 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.

Catalyst Edit holds the better App Store score, 4.7 against 3.4. That said, the two scores are not equally well evidenced: Catalyst Edit has 254 ratings behind it against 23, so its average is the more settled of the two. Written reviews complicate that: 27% of Catalyst Edit's written reviews are positive against 47% of REACTOR's, so the app with the better star average is not the one people write more warmly about.

Catalyst Edit ships an update monthly, REACTOR every 3 weeks. The most recent releases landed on October 10, 2026 and October 8, 2026 respectively.
