# ReTrader vs Penn Mobile

The clearest difference is rating: Penn Mobile at 4.6 against ReTrader's 3.0. Penn Mobile also leads on in-app purchases (none vs 10) and ratings volume (410 vs 2). ReTrader's advantage is review sentiment (82% vs 53%) and iOS requirement (13.0 vs 17.6). On price, ads and device support there is nothing between them.

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

Penn Mobile holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: Penn Mobile has 410 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 53% of Penn Mobile'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, Penn Mobile monthly. The most recent releases landed on October 9, 2026 and October 24, 2026 respectively.
