# goREACT vs DAC App

The clearest difference is rating: goREACT at 2.2 against DAC App's 1.8. goREACT also leads on update cadence (every 4 months vs every 12 months) and ratings volume (99 vs 16). On price, review sentiment, 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.

goREACT holds the better App Store score, 2.2 against 1.8. That said, the two scores are not equally well evidenced: goREACT has 99 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 18% of goREACT's written reviews are positive against 20% of DAC App's, so the app with the better star average is not the one people write more warmly about.

goREACT ships an update every 4 months, DAC App every 12 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
