# DukeMobile vs ReTrader

The clearest difference is rating: DukeMobile at 3.7 against ReTrader's 3.0. DukeMobile also leads on in-app purchases (none vs 10) and ratings volume (28 vs 2). ReTrader's advantage is review sentiment (82% vs 72%) and iOS requirement (13.0 vs 17.0). On price, update cadence, ads and device support there is nothing between them.

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

DukeMobile holds the better App Store score, 3.7 against 3.0. That said, the two scores are not equally well evidenced: DukeMobile has 28 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 72% of DukeMobile's written reviews are positive against 82% of ReTrader's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on August 1, 2026 and July 26, 2026 respectively.
