# ReTrader vs CourseGrab

The clearest difference is review sentiment: ReTrader at 82% against CourseGrab's 25%. ReTrader also leads on update cadence (every 2 months vs every 6 months) and device support (3 vs 1). CourseGrab's advantage is rating (3.6 vs 3.0) and in-app purchases (none vs 10). On price and ads there is nothing between them.

Both are free to download. ReTrader sells 10 one-off in-app purchases. CourseGrab asks for nothing beyond the download.

CourseGrab holds the better App Store score, 3.6 against 3.0. That said, the two scores are not equally well evidenced: CourseGrab has 17 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 82% of ReTrader's written reviews are positive against 25% of CourseGrab's, so the app with the better star average is not the one people write more warmly about.

ReTrader ships an update every 2 months, CourseGrab every 6 months. The most recent releases landed on July 26, 2026 and August 18, 2026 respectively.
